Calculating the Number of Boys in the Primary School

To calculate the number of boys in the primary school, we can use the information provided about the total number of students and the proportion of girls.

Given: - Total number of students in the primary school: 187 - Proportion of girls: 9/17

We can calculate the number of boys using the following steps:

1. Calculate the Number of Girls: - Number of girls = Total number of students * Proportion of girls - Number of girls = 187 * (9/17) = 99

2. Calculate the Number of Boys: - Number of boys = Total number of students - Number of girls - Number of boys = 187 - 99 = 88

Therefore, there are 88 boys in the primary school.
