Question

A ratio of boys to girls in a school is 9/10 if there are 300 girls at the school. How many total students are there in the school?

Answer 1

There are 570 total students in the school

Explanation:

Step 1: Determine how many boys are in the school:

Since the ratio of boys to girls is 9 boys:10 girls and there are 300 girls, we can determine how many boys (b) are in the school using a proportion:

`(9)/(10)=(b)/(300)\\ \\ (10*b)=(300*9)\\\\(10b=2700)/10\\\\b=270`

Thus, there are 270 boys in the school.

Step 2: Determine the total number of students in the school:

Now we can determine the total number of students in the school by adding 300 and 270:

Total number of students = 300 girls + 270 boys

Total number of students = 570

Thus, there are 570 total students in the school.
