You can put this solution on YOUR website! there are 50 students in a class, 2/5 of them are boys * 50 = 20 boys
:
& 25% of the boys are black.
.25 * 20 = 5 boys are black
:
If there are 15 black students in the class,
50 - 15 = 35 white students
:
then how many girls are in white?
Find the number of white boys
20 - 5 = 15 white boys
then
35 - 15 = 20 girls are white
