Jair Sweeney · Answer 1

To find t he total number of girls in the school divide the number of girls present by the percentage present.

816 / 0.8 = 1020

There are a total of 1020 girls.

Now to find the total enrollment, divide the total number of girls by the percentage of girls total:

1020 / 0.40 = 2550

There are a total of 2550 students.
