Calculating Half of a Fraction

Hard Number Concepts And Operations Fractions

Alice has a recipe that requires two-thirds (or $$\f\frac{2}{3}$$) of a cup of sugar. If she wants to make only half of the recipe, how much sugar will she need?

To find the amount of sugar needed for half the recipe, you must multiply the original amount of sugar by $$\f\frac{1}{2}$$.

One-third of a cup $$\left(\frac{1}{3} \text{ cup}\right)$$

One cup $$\left(\frac{1}{1} \text{ cup}\right)$$

Three-quarters of a cup $$\left(\frac{3}{4} \text{ cup}\right)$$

One cup and a half $$\left(\frac{3}{2} \text{ cups}\right)$$
