Answer:

Test the two ratios/fractions to see whether they are equivalent by multiplying diagonally (cross multiply). 3 4 = 15 20 4 * 15 = 60 and 3 * 20 = 60.

This is a proportion. If the two numbers that are diagonal result in the same answer when they are multiplied, you are working with a proportion.
