show the work (use proportion)

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%

Make fraction and multiply by 100% 42/150 * 100% = 4200/150% = 28%28% people wear contact lenses
