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.

Explanation

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 multiply $\frac{35}{8}$ cups by 10.

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.
