In a school orchestra, the ratio of girls to boys is 3 : 2. There are 75 students in the orchestra. How many boys are in the orchestra?

Respuesta :

Answer:

45 boys -- 30 girls

Step-by-step explanation:

Add the ratio number 3+2=5

Divide: 75/5=15

Multiply by the numbers in the ratio:

3x15=45 boys

2x15=30 girls
There are 3 girls to every 2 boys, so our equation is 3g+2b=75.

First we are going to do 3+2=5
Then 75/5=15
Then we want to put 15 where our variables are and solve the equation.
3(15)+2(15)=75
45 + 30 = 75

The equation is true, so the answer is that there is 45 girls and 30 boys
