Best friends Olivia and Syliva both get a weekly allowance are in the ratio 2:3if Syliva gets 21 dollars one week how much did Oliva get.

Answer 1

To find out how much Olivia got, we need to find the ratio between Olivia and Sylvia's amounts in the same way.

The ratio between Olivia and Sylvia is 2:3.

Let's set up a proportion to find out how much Olivia got.

2/3 = x/21

To solve for x, we can cross multiply.

2 * 21 = 3 * x

42 = 3x

To isolate x, we divide both sides by 3.

42/3 = x

14 = x

Therefore, Olivia got $14.
