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

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%

Just add % to the 22

Your answer is 22%
