Question

In one middle school, there are 9 girls for every 6 boys. The total number of students is 550.

Estimate the number of girls in the school.

Answer 1

There are about 330 girls in the school

Explanation:

First, we need an equation to represent the scenario:

9x + 6x = 550 students

Add like-terms:

15x = 550

Divide to isolate the variable:

x = 36.6666667

Multiply x by 9:

36.6666667 * 9 = 330
