Answer 1

Step-by-step answer:

If there are 40% students that are girls , and the rest are 250 boys. Then that must mean there are 60% boys. Because that is the compliment.

i)

Because we know that 60% of the people in the group are boys, and that the amount of boys amounts to 250, we can model an equation like this.

$Total * 0.6 = 250$.

$Total = 250/0.6$

$Total = 417$

There are 417 students

ii)

Because we know that the total amount is 417, we can find the amount of girls there are by multiplying the total by the percentage.

$417 * 0.4 = 167$

There are 167 students that are girls.
