1. We can start by using the ratio to find the fraction of girls in the school:

girls : boys = 5 : 4

This means that out of every 5 + 4 = 9 students, 5 of them are girls. So the fraction of girls is:

5/9

To find out how many students are girls in a school with 918 students, we can set up a proportion:

5/9 = x/918

where x is the number of girls.

To solve for x, we can cross-multiply:

5 × 918 = 9 × x

4590 = 9x

x = 4590/9

x = 510

Therefore, there are 510 girls in the school.
