Question

There are 16 boys and 18 girls in the classroom. .What is the ratio of boys to girls in simplest form?

A. 2:3
B. 4:3
C. 3:4
D .8:9

Answer 1

Answer: Choice D. 8:9

Work Shown:

16 boys: 18 girls

16:18

16/2:18/2

8:9

I divided both parts of the ratio by the GCF 2 in order to reduce from 16:18 to 8:9. For every 8 boys there are 9 girls.
