# How do you simplify to tell whether the ratios #2/8, 5/20# form a proportion?

Explanation below.

To compare two fractions, we need to make their denominators the same. To do so, multiply both the numerator and the denominator of each fraction, so that their denominators are equal, then compare the numerators:

The fractions are equivalent (and equal), and thus, they form a proportion.

To determine if the ratios 2/8 and 5/20 form a proportion, you need to cross multiply and check if the products are equal. If they are, then the ratios form a proportion.

For 2/8 and 5/20:

(2 * 20) = (8 * 5) 40 = 40

Since the products are equal, the ratios 2/8 and 5/20 form a proportion.
