If there are 40% of girls and 250 are boys, find
oee [108]

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.
