A pizza dough recipe calls for 6 1/2 cups of flour. The recipe makes 37 1/2 ounces of dough. How many ounces of dough does 1 cup

NemiM [27]

Answer:

$n = 5\frac{10}{13}$

Step-by-step explanation:

Given

$Call = 6\frac{1}{2}$ cups

$Recipe = 37\frac{1}{2}$ ounce

Required

Number of ounces per cup (n)

To do this, we simply divide the Recipe by the call

So, we have:

$n = \frac{Recipe}{Call}$

$n = 37\frac{1}{2} \div 6\frac{1}{2}$

Express as improper fraction

$n = \frac{75}{2} \div \frac{13}{2}$

Rewrite as:

$n = \frac{75}{2} * \frac{2}{13}$

$n = \frac{75}{13}$

$n = 5\frac{10}{13}$
