This information is enough to set up one ratio comparing the number of hours worked to the amount of money made.The rest of the information that we have is that next week you will be working 31 hours, and you want to know how much money you'll make for that many hours.so you need twice as much of everything to keep the ratio.Tags: Discursive Essay Plan Higher EnglishStewart Calculus 7e Homework HintsCourage Mockingbird EssayLife Lessons That College Teaches You EssayHelp Writing Term PaperAssignment 1Adventures Of Huckleberry Finn EssayTobacco Tax EssayBachelor Thesis Science FictionWriting Skills Essay Penn Foster
It is important to note that you want your quantities in the numerator and denominator to be consistent in both ratios of the proportion.
We see that we did this with our example, since hours is in the numerator in both ratios and dollars is in the denominator in both ratios.
Then we set the two products equal to each other and solve for the unknown. We can use proportions to solve this problem, but first we have to construct the proportion that represents this problem.
To construct a proportion, we just need to set up two ratios comparing the same quantities and then set them equal.
Once again, we have a real world problem that we can use proportions to solve.
First, we need to construct our proportion, so we need two ratios. This gives us two quantities to put together in a ratio. A proportion is an equation in which two ratios are set equal to one another, and a ratio is a fraction comparing two quantities.

Multiply across the known corners, then divide by the third number: Part = (160 × 25) / 100 = 4000 / 100 = 40 Answer: 25% of 160 is 40.
This tutorial let's you see the steps to take in order to turn a word problem involving a blueprint into a proportion. That's why proportions are actually equations with equal ratios.
Ingredients sometimes need to be mixed using ratios such as the ratio of water to cement mix when making cement. Then think of some ratios you've encountered before!
