Question

The ratio of red jellybeans to yellow jellybeans to blue jellybeans in a bowl is

3:2:5. If there are a total of 80 jellybeans, then how many of each color is in the bowl?

Answer 1

see explanation

Explanation:

Sum the parts of the ratio, that is 3 + 2 + 5 = 10

Divide the total jellybeans by 10 to find the value of one part of the ratio

80 ÷ 10 = 8 ← value of 1 part of the ratio, thus

red jellybeans = 3 × 8 = 24

yellow jellybeans = 2 × 8 = 16

blue jellybeans = 5 × 8 = 40
