Ratio, Proportion, & Percent

2. Complete the following worksheets and scroll down for the answers. Remember that in math,"of" means "multiply." So if the problem asks you to figure out what is 3/8 of 128, you should multiply.

If it helps, go right to the question at the end of the problem first, and create a "word ratio" to use as your template. For example, for Problem 1a in the first worksheet, you can see that what they want is the ratio of green marbles to all the marbles. You can write "green"/"all" and then you're ready to create your fraction (of numbers) to go with it. Don't forget to reduce your answer to simplest form.

1. "Solve Ratio and Proportion Problems" worksheet. Remember to set up a proportion using equivalent ratios. It helps if you create a "word" ratio first, showing which category is on the top and which is on the bottom. For example, you might put "inches" (numerator, top) to "miles" (denominator, bottom). Then you will know where to put your numbers and your missing value, x. Find x through Cross Multiply & Divide method.

2. "Apply the Strategy" has two pages of percent problems to do. Remember that for those proportions, you can put the 100 in the bottom right fraction to get you started. That's your "percent" fraction. The first fraction will be your "part/whole" fraction. Then Cross Multiply & Divide to find your answer.
