received 15 first-place ribbons and 27 second-place ribbons

ner apple pie. Have Ms. Edwards and Ms. Bowen won equal

ratios of ribbons? Explain.

Ms. Edwards and Ms. Bowen won equal ratios of ribbons that is 5 : 9

Solution:

We need to check if Ms. Edwards and Ms. Bowen won equal ratios of ribbons

Calculating ratio of ribbons for Ms. Edwards

Number of first-place ribbons won by Ms. Edwards = 10

Number of second-place ribbons won by Ms. Edwards = 18

So for Ms. Edwards,

Ratio of first-place ribbons : second place ribbons = 10 : 18 = 5 : 9

Calculating ratio of ribbons for Ms. Bowen

Number of first-place ribbons won by Ms. Bowen = 15

Number of second-place ribbons won by Ms. Bowen = 27

So for Ms. Bowen,

Ratio of first-place ribbons : second place ribbons = 15: 27 = 5 : 9

As ratio of first-place ribbons and second place ribbons for both Ms. Edwards and Ms. Bowen is 5 : 9 so we can conclude that Ms. Edwards and Ms. Bowen won equal ratios of ribbons.
