There are 420 students in a school. if 40% of them are girls. find the number of girls and boys

Answer: 252 Boys, 168 Girls

Step-by-step explanation:

420 would be 100% of the school students.

If you wanna find the number of girls, you need to divide 420/100 in order to get 1% and then multiply it by 40.

So then you would get

420/100 x 40 = 168

Then in order to get the boys just subtract 168 from 420

420 - 168 = 252

There would be 168 girls and 252 boys

Step-by-step explanation:

40% or 0.40 x 420 = 168

420 - 168 = 252
