Question

In a group of 105 children, 22 have green eyes. What percent have green eyes?

Answer 1

Just add % to the 22
Your answer is 22%

Answer 2

So percent means parts out of 100
so x%=x/100
22 out of 105 have green eyes
22/105
we want to find an equivilent fraction that has 100 in the bottom that is equal so 22/105
22/105=x/100
solve for x
multiply both sides by 100 to clear fraction
2200/105=x
simplify
20.95=x
round up
21
answe ris 21%
