Since the ratio is 3:4, and 12/4 is 3 than you do 3x3 and get 9 so the answer is 9:12 or 9 boys and 12 girls. To check your answer, you can do 3/4 (for 3:4) and that is 0.75. If you do that with 9:12 you also get 0.75.

Answer:

There are 9 boys in the choir

Step-by-step explanation:

Boys : Girls = 3 : 4

Substitute in 12 for girls and represent new value for boys as x

3 : 4 = x : 12

Write as fractions

3/4 = x/12

Cross-Multiply (numerator * denominator / numerator * denominator)

3(12) = 4(x)

36 = 4x

Divide both sides of the equation by 4

x = 9

There are 9 boys in the choir

Hope this helps :)
