42 of the 150 employees at Carlo's Car Repair wear contact lenses. What percent of the employees wear contact lenses?

1 answer:

6 0

$\frac{42}{150}$ ÷ 2 = $\frac{21}{75}$

$\frac{21}{75}$ ÷ 3 = $\frac{7}{25}$

$\frac{42}{150}$ = $\frac{7}{25}$

Then, divide 7 by 25 because 25 is the divisor

7 ÷ 25 = 0.28

28% is the answer (:
