Answer:
There are 22 girls and 33 boys.
Step-by-step explanation:
Let b be the number of boys and g the number of girls.
We are told that:
b = (3/2) g
b + g = 55
Substituting the first equation into the second:
(3/2) g + g = 55
=> (5/2) g = 55
=> g = 55 × 2 / 5 = 11 × 2 = 22
and b = 55 - g = 55 - 22 = 33.
