Contact [7]

Answer:

3

Drink mix ratio:

Lemonade : Orange : Cranberry

6 : 3 : C

Fraction of Cranberry juice = $\frac{3}{12}$

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

Fraction of Cranberry;

$\frac{C}{9 + C}$ = $\frac{3}{12}$

3(9 + C) = 12C

27 + 3C = 12C

27 = 12C - 3C

9C = 27

C = 3

The missing number will be 3
