At chestatee middle school, 120 students are in the choir. the ratio of girls to boys in the choir is 5: 3. what is an equation that represents the number of boys in the chor in terms of of the number of girls?

An equation to represent the number of boys could be:
b = (15/8)g

Since the ratio of boys to girls is 5:3, we should divide 120 by 8 (the combined total) so we can determine the number of boys and girls.

120 / 8 = 15

For the boys, 5 x 15 = 75
For the girls, 3 x 15 = 45

There are 75 boys and 45 girls in the choir. Now, we have to write an equation.

g x k = b
45 x K = 75
K = 75/45 or 15/8

Our final equation will be b = (15/8)g

Where are the functions?
