Answer:
7.2 which will round down to 7 boys
Step-by-step 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
