Question

A recipe requires \frac{1}{4}1414 cup of water for each \frac{1}{3}1313 cup of milk. How many cups of water are needed for each cup of milk?

Answer 1

1/4 cup of water----------------------->1/3 cup of milk

x cups of water------------------------> 1 cup of milk

using cross-multiplication:

`\begin{gathered} ((1)/(4))/(x)=((1)/(3))/(1) \\ solve_{\text{ }}for_{\text{ }}x\colon \\ x=((1)/(4))/((1)/(3)) \\ x=(3)/(4) \end{gathered}`
