Question

The ratio of girls to boys at a school dance is 3 to 2. There are 54 boys at the dance. How many girls are at the dance

Answer 1

There are 81 girls.

Explanation:

First, take what we know and find how many people 1 in the ratio is:

54 / 2 = 27

(in this problem) 1 = 27

Now find how many girls are at the dance by multiplying by three:

27 x 3 = 81

There are 81 girls at the dance.
