The ratio of girls to boys in the school is 5:6, which means that for every 5 girls, there are 6 boys.
Since we know that there are 20 girls in fifth grade, we can set up a proportion using the ratio:
5 (girls) / 6 (boys) = 20 (girls) / x (boys)
Cross-multiplying, we get:
5x = 20 * 6
5x = 120
Dividing both sides by 5, we find that:
x = 120 / 5
x = 24
Therefore, there are 24 boys in the fifth grade.
So the correct answer is 24 boys.
if the ratio of girls to boys in the school is 5:6 and there are 20 girls in fifth grade, how many boys are in the fifth grade?
12 boys
