make fraction and multiply by 100% 42/150 * 100% = 4200/150% = 28%28% people wear contact lenses
so you need to find the percentage of 42/150
first, we need to simplify the question to solve the problem more easier.
42/150 ÷ 2 = 21/75
21/75 ÷ 3 = 7/25
42/150 = 7/25
to make it into a percent, you need to divide 7 by 25 because 25 is the divisor.
7 ÷ 25 = 0.28
and we need to move the decimal twice to the right. the answer is= 28%
