Algebra-1

The ratio of girls to boys is 7 to 5. This means that for every 7 girls, there are 5 boys.

Given that there are 210 girls in the school, we can find the number of boys:

7 girls / 5 boys = 210 girls / x boys

Cross-multiplying, we get:

7x = 5 * 210

7x = 1050

x = 1050 / 7

x = 150

Therefore, there are 150 boys in the school.
