A.What is an equation that represents the total number of girls and boys in choir? Be sure to define the variables you use.
B. What is an equation that represents the number of boys in the choir in terms of the number of girls? Show or explain your work

Answer 1

The correct answer should be:
(3g)/5

Answer 2

Let the total number of students be x;
given that the ratio of girls to boys is 5:3, then:
The equation that represents the number of girls will be:
5/8x
The equation that represents the number of boys will be :
3/8x
The equation that represents the total number of boys and girls will be:
5/8x+3/8x

B] suppose there are g number of girls. The equation that represents the number of boys in terms of number of girls will be:
(ratio of boys to girls)×(number of girls)
3/5×(g)
=(3g)/5
