Adım Adım Çözüm

Set up a proportion based on the ratio of orange juice to cranberry juice.

\frac{3}{4} = \frac{12}{x}

where

x

represents the number of cups of cranberry juice.

The ratio of orange juice to cranberry juice is constant at 3 to 4.

Solve the proportion for

x

by cross-multiplying.

3x = 12 \times 4

3x = 48

Cross-multiplication is a standard method to solve proportions.

Divide both sides by 3 to isolate

x

x = 16

Isolating the variable gives the required amount of cranberry juice.
