Question

Luis has a recipe that requires 2 cups of milk. He knows that 1 cup = 8 ounces.How many ounces of milk does Luis need for the recipe?

Answer 1

1 cup is equivalent to 8 ounces.

To find how many ounces are equivalent to 2 cups, we can use the next proportion:

$\frac{1\text{ cup }}{2\text{ cups}}=\frac{8\text{ ounces}}{x\text{ ounces}}$

Solving for x,

$\begin{gathered} 1\cdot x=8\cdot2 \\ x=16\text{ ounces} \end{gathered}$
