Question

A survey found that 12 out of every 15 people prefer eating out over cooking. If 500 people took the survey, how many people prefer eating out?

Answer 1

Divide 500 by 15 that equals 33.33 then multiply that number by 12 and that equals 399.96 which is then rounded up to 400/500 people prefer eating out rather than cooking at home.

Answer 2

400 people

Explanation:

15 = 12

500 = x

Cross multiply

15x = 12 × 500

Divide both sides by 15

`(15x)/(15)` =
`(12 * 500)/(15)` (* means multiplication if you do not know)

`(12 * 500)/(15)` = 100 × 4= 400 people
