Question

In a group of 40

people, 22 of them
have brown hair.
What percent of
them don't have
brown hair?

Answer 1

To determine the percentage of people without brown hair in a group of 40 where 22 have brown hair, we subtract 22 from 40 to find that 18 people don't have brown hair. Then we divide 18 by 40 and multiply by 100 to get 45%.

Step-by-step explanation:

To find what percent of the 40 people do not have brown hair, we first need to deduct the number of people with brown hair from the total group size. Then, we calculate the percentage of the remaining people based on the total group size. In this case, 22 people have brown hair, so we subtract this number from the total of 40 to find that 18 people do not have brown hair.

Next, to calculate the percentage, we divide the number of people without brown hair (18) by the total number of people (40) and then multiply by 100:

(18 / 40) * 100 = 45%

Therefore, 45% of the group do not have brown hair.

Answer 2

Step-by-step explanation:

Hi:

First determine those without brown hair:

40-22=18 don't have brown hair.

18/40 don't have brown hair:

Divide by 2

9/20

Multiply by 5 to get percent

45/100= 45 percent don't have brown hair
