The sections on Mixtures and Work simply add one or two steps from your previous knowledge from Chapters 3 and 4. Answer the following questions to help you address your issues with these types of problems.
1) Are mixture problems difficult to set up in a chart? Why or why not? Will you always need an extra 3rd row in your chart?
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?

1) I think mixture problems are difficult to set up in a chart because I'm not sure what and where to label things. And I will not always need an extra 3rd row in my chart.
ReplyDelete2) I think work problems are not difficult to set up in a chart because there is a certain formula that you have to memorize and apply. You just have to remember to put work rate as a fraction and multiply work rate and time to get work done.
3) I think decimals are more difficult, because the decimal points are confusing to me and I like to multiply with fractions better.
1) I think mixture problems are difficult to set up in a chart because I don't understand where to label things. I don't think I will always need an extra third column in my chart.
ReplyDelete2)I think word problems are difficult too. I find it hard to understand the situation in some problems.
3)I think problems that use decimals are much harder because I make mistakes when calculating them. I find problems using fractions much easier.
1)For me, setting up a chart for mixture problems is quite difficult,because the details of those problems are normally complex. I probably will "always" need an extra 3rd row in my chart for mixture problems, because there's always the original, amount of change, and new.
ReplyDelete2) Usually work problems aren't that difficult to set up in a chart. If I just follow steps from classes, most question are usually solved without any issues. One certain type of question I have the most difficulty is questions about works, like work combination. "A can work this much, B can work this much.If they work together.."
3) Decimals is "normally" harder to use since I'm not that great at calculating. Still, if the fraction is completely strange and out of my reach, decimals is my solution that I use.
1)I'm not sure about others but for me, making the charts aren't that hard. My main problem mostly deals with making the equation and solving them. But mainly dealing with making the equation. And for most of the problems, we needed to make the third chart in order to make the equation.
ReplyDelete2)for work problems, since we only need to put in work rate X time = work so the chart isn't too hard but as same as the mixture problems, it isn't too easy making the equations and solving them.
3)Personally, I think decimals are harder since I actually have to solve while with fractions, I could simplify, cross multiply, and other fraction methods.
1) It is a little confusing at first, but once the first two rows are set up it all falls into place. I think a 3rd row can be taken out and done mentally, but I don't think I can do that yet.
ReplyDelete2) They are only difficult when the wording is tricky, and sometimes I just get a weird answer because I didn't know at all what the question meant. I always think to myself to think outside the box when I'm reading a word problem, to think about it every single possible way.
3)Fractions are more easier to work with because they are easier to memorize, so I don't have to look at the problem over and over again. Decimals are a little harder because they have more digits, but overall they are about the same.
1) I found it a little confusing when setting up the charts because I had a difficult time labeling the the different rows and columns according to the word problem. Probably we would always need a third column since we need that information to come up with an equation.
ReplyDelete2) I think the Work charts are easier than the Mixture charts because it is more easier to plug in the information from the word problem into the chart. All we have to remember when making Work charts is that the Work Rate is in fractions.
3) I am more comfortable with fractions than with decimals because the different decimal points lead me to make mistakes during calculation.
1) Mixture problems are not hard for me as when i get the exact information in right place in chart, answer can be easily earned. The extra 3rd row will depend on the question, yet most of the time there will be the extra 3rd row.
ReplyDelete2) No, if the work problem is interpreted well, it can be very easy to solve through using charts. I usually try not to miss any information.
3)Decimals are harder as fraction is easy to divide and multiply.
1. I think these mixture problems differ by the complexity of the problem. If there are a lot of bars to fill out, I was sometimes confused of what to put. But, it was easier for me when it was a small and simple problem, however if it is very complex, I would be confused a lot.
ReplyDelete2. Like I've said, it all depends on the complexity of the problem, if it requires you to solve and fill the chart up with more information, I would be having so many problems trying to solve out.
3. I think decimals are easier for me because when I multiply or calculate problems that require only basic math skills, it would be fast too. Also, when your doing it with fractions, I am kind of lazy to simplify the questions.
1. Mixture problems are sometimes hard and sometimes easy, and for me, it always depends on the complexity of the question because if it is more complex, it requires more thinking and skills to fill out the chart accurately, but if it is a simple and short question, I wouldn't have as much troubles as others.
ReplyDelete2. Yes and No, because when I read the question and depending on the complexity of the question, I can solve easily or hardly. However, rather than making equations, it is more accurate to make charts.
3. Decimals are easier because even if it gets complicated by a very small number, you can always multiply 10, 100, etc, to make the equation simpler. And fractions are personally boring because they have to simplify.
1) Are mixture problems difficult to set up in a chart? Why or why not? Will you always need an extra 3rd row in your chart?
ReplyDelete3rd rows may not be always in need; however, they are used frequently in terms of calculating the total concentration. This makes mixture problems harder because you have to calculate for both the concentration and the amount of water or other materials are used up or accumulated.
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
Some are easy because you only need to put in the numbers and variables to solve. On the other hand others have unknown parts which I must find by interpreting the data on the chart, which makes it more complicated than just simply writing equations.
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?
Mixture problems are much harder because decimals have to be linked with percentage and the concentration of a material in water or any liquid must all be calculated individually. This makes it have more steps to solve the question.
1) I wasn't used to making charts at first but I got used to it as I practiced solving problem in this way. A 3rd row is used often but not always. Since it needs to find the different solute in the solvent it may need the 3rd row.
ReplyDelete2) I think that the difficulty of making a chart for word problems depend on each one. If it includes several variables to solve the answer, it may take more time than usual. I always remember to use the chart to form a equation.
3) I think that the work problems are easier than the mixture problems. For me, using fractions to solve the answer is more comfortable. Also each factor must be multiplied by the decimal to get a final amount of something. In conclusion it would take more time and take up more steps to finish a mixture problem.
1. I think that Mixture problems are a little difficult for me since I am sometimes confused where to label and input my numbers. Also, we don't always need a third row.
ReplyDelete2. Work problems are not difficult and they are actually easy compared to mixture problems. We always have to remember the equation: Work rate * Time = work distance.
3. Mixture problems using decimals are harder to solve than fractions.It is because I have to solve it and is more complicated compared to using fractions
1) Are mixture problems difficult to set up in a chart? Why or why not? Will you always need an extra 3rd row in your chart?
ReplyDeleteIt is not all that hard because we have done charts for other chapters too. The number of rows depend on the question.
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
Sometimes because they describe it in a roundabout way. I think about trying to translate it into numbers and that helps.
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?
Decimals are harder for me because I usually work with fractions more than decimals.
1) Are mixture problems difficult to set up in a chart? Why or why not? Will you always need an extra 3rd row in your chart?
ReplyDeleteI think it depends on the problem because if questions are complicated than it is hard to organize. For the chart I think it depend on the problem and you
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
It is hard because it is not easy to understand main points. You need to remember the main things of the question to solve
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?
I think decimal is more hard to solve because fraction you can make it into decimal later on and you can simplify and it makes easy to divide
1) Are mixture problems difficult to set up in a chart? Why or why not? Will you always need an extra 3rd row in your chart?
ReplyDeleteNo, I do not think putting the number in charts are hard, because it depends on the question. I will need an extra 3rd row depending on the question.
2) Are work problems difficult to set up in a chart? Why or why not? What things do you always have to remember for these types of problems?
I think that work problems are not difficult to set up in a chart, because rate X time = distance traveled can be put in a chart. For these type of problems you have to remember rate and time.
3) For mixture problems, we usually use decimals. For work problems, we use fractions. Which one is more difficult for you to solve? Why?
I think mixture problems are more difficult, because there is more steps, and thinking involved to solve the problem.

I think mixture problems are more difficult, because there is more steps, and thinking involved to solve the problem.
1) Mixtures are sometimes difficult to set up in a chart. Sometimes, I don't know what goes in what box. Also, I sometimes only make 2 rows and I forget to make the 3rd row. No, sometimes I don't need 3 rows in my chart
ReplyDelete2) Work problems are sometimes hard to set up in a chart. I don't get the reason why I need to make the rate in a fraction. Also, it is sometimes hard to know what should be x. In these kinds of problems, I need to know that I have to make the rate be a fraction and what I am looking for
3) I think it is harder to solve mixture problems because I don't like solving decimals and I prefer fractions.
