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

Answer 1

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:

#2/8 = (2*5)/(8*5) = 10/40# #5/20 = (5*2)/(20*2) = 10/40#

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.

To determine if the ratios 2/8 and 5/20 form a proportion, you can cross multiply and check if the products are equal. In this case, 2 * 20 = 40 and 8 * 5 = 40, so the products are equal. Therefore, the ratios form a proportion.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
