Question

`27 1/2%` of what number of people is `11` people?

Answer 1

The count of all people is 40

Explanation:

Write `27 1/2%` as `27.5/100`

I much prefer to work in whole numbers if I can

`27.5/100 = (27.5xx2)/(100xx2)=55/200`

Let the total count of people be `x`

Then:`" "55/200xx x =11`

`=>x=11xx200/55 = 40`
