This question is If there are 320 students in the 5th grade and there are 20 more boys than girls, how many boys are there? How many girls are there?

of the total 320 boys & girls, set aside 20 as the 'extra' boys.

that leaves 300 kids; half are boys, half are girls.

Therefore there are 150 girls & 170 boys.
