In a class there are 12 girls. If the ratio of boys to girls is 5:4.. how many boys are there in the class

1 answer

Given that the ratio of boys to girls is 5:4 and there are 12 girls in the class.

Let x be the number of boys in the class.

According to the ratio, the number of boys is 5 times the number of girls. So,

x = 5 * 12/4
x = 15

Therefore, there are 15 boys in the class.
