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.
