# A recipe for cake needs 3/4 of a cup of milk. You are making 1/2 of the recipe. How much milk do you need?

$\frac{3}{8}$ of a cup.
You want half of the recipe, so you want half of $\frac{3}{4}$ of a cup.
Of means multiplication when it comes to fractions, so multiply $\frac{3}{4}$ by $\frac{1}{2}$ to get
$\frac{3}{4} \cdot \frac{1}{2} = \frac{3}{8}$
