Answer: D (2 cups)

Answer 2

If a recipe calls for $2\dfrac{2}{3}$ cups of flour and Terell wants to make $\dfrac{3}{4}$ of the recipe, then in order to determine how much flour he should use, he has to multiply $2\dfrac{2}{3}$ by $\dfrac{3}{4}$.

Note that

$2\dfrac{2}{3}=\dfrac{2\cdot 3+2}{3}=\dfrac{8}{3}.$

Therefore,

$2\dfrac{2}{3}\cdot \dfrac{3}{4}=\dfrac{8}{3}\cdot \dfrac{3}{4}=\dfrac{8\cdot 3}{3\cdot 4}=2$ cups of flour.

Answer: 2 cups of flour - choice D
