The ratio of boys to girls in a choir is 3 to 9. There are 45 girls in the choir, how many members are in the choir?

There are 15 boys in the choir

Step-by-step explanation:

If there are 45 girls in the choir and the ratio of boys to girl is 3 to 9, you would have to multiply the 9 by 5 to get 45. You have to do the same thing to both sides so you would also multiply the 3 by 5 to get 15. The new ratio is 15 to 45.
