It takes 4 3/8 cups of cheese,7/8 cups of olives,and 2 5/8 cups of sausage to make a signature pizza. How much cheese is needed
Crank

43\frac{3}{4} cups of cheese is needed to make 10 pizzas.

<u><em>Explanation</em></u>

For making one pizza, amount of cheese needed = 4\frac{3}{8} cups = \frac{35}{8} cups.

Now for finding the total amount of cheese needed to make 10 pizzas, we need to <em>multiply \frac{35}{8} cups by 10. </em>

So, (\frac{35}{8}*10)cups= \frac{350}{8}cups= \frac{175}{4}cups= 43\frac{3}{4} cups

Thus, 43\frac{3}{4} cups of cheese is needed to make 10 pizzas.
