a cookie recipe calls for 2 1/2 cups of sugar for every 2/5 cup of flour. if you made a batch of cookies using 1 cup of flour how many cups of sugar would you need?

Respuesta :

[tex]\bf \begin{array}{ccllll} sugar&flour\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ 2\frac{1}{2}&\frac{2}{5}\\\\ x&1 \end{array}\implies \cfrac{2\frac{1}{2}}{x}=\cfrac{\frac{2}{5}}{1}[/tex]

solve for "x"
