Question

The ration of female to male shoppers at a department store has been found to be 10 to 9. If 1,188 male shoppers were at the store one Saturday, how many shoppers were there in all that day?

Answer 1

2,508 shoppers

Explanation:

Ratio of female to male : 10:9

Let F be the number of female shoppers and M be the number of male shoppers

That can be expressed as

`(F)/(M)= (10)/(9)`

Given M = 1188

`(F)/(1188)= (10)/(9)`

Multiply both sides by 1188


`(F)/(1188) * 1188= (10)/(9) * 1188\\\\F = 1,320`

Total number of shoppers = M + F
= 1188 + 1320
= 2,508 shoppers
