Question: How do I do fractions and proportions?

To solve this proportion, you have to cross multiply, and to do fractions, make sure the bottom numbers (the denominators) are the same, and the top numbers (the numerators) put that answer over the denominator, and simplify if need be.

You have to have both fractions next to each other.

Cross multiply (the top right number times the left bottom number) and the multiply the right bottom number times the left top number)

and see if they equal the same number if not than that is not proportional.
