Question

A class contains 24 students 30 % of them are boys
how many boys are there in the class

Answer 1

7.2 which will round down to 7 boys

Explanation:

30% in decimal form is .3

You multiply the .3 by 24 to get 7.2.

Since you cannot have a .2 of a person there are seven boys.

7 boys = 29.17%

8 boys = 33.33%

those are the percent of the class the boys would take up if there were those many boys
