Question

The ratio of boys to girls at Highland

Secondary School is 3 to 4. If there are
435 boys at the school, determine the
school's entire population.

Answer 1

The entire population of the school is 1015.

Step-by-step explanation:

To determine the entire population of the school, we need to find out the number of girls first. The ratio of boys to girls is given as 3 to 4. Therefore, the ratio of boys to the entire population is 3 to 7 (boys + girls). We know that there are 435 boys, so we can set up a proportion:

3/7 = 435/x

Cross-multiplying, we get:

3x = 7 * 435

Simplifying, we find that the entire population of the school is 1015.
