Question

A drink is mixed in the ratio

lemonade : orange : cranberry = 6 : 3 : ?
If the fraction for cranberry juice is 3/12, what would be the missing number in the ratio?

Answer 1

3

Explanation:

Drink mix ratio:

Lemonade : Orange : Cranberry

6 : 3 : C

Fraction of Cranberry juice =
`(3)/(12)`

Sum of the ratio = 6 + 3 + C = 9 + C

Fraction of Cranberry;

`(C)/(9 + C)` =
`(3)/(12)`

3(9 + C) = 12C

27 + 3C = 12C

27 = 12C - 3C

9C = 27

C = 3

The missing number will be 3
