[tex]43\frac{3}{4}[/tex] cups of cheese is needed to make 10 pizzas.
Explanation
For making one pizza, amount of cheese needed = [tex]4\frac{3}{8}[/tex] cups = [tex]\frac{35}{8}[/tex] cups.
Now for finding the total amount of cheese needed to make 10 pizzas, we need to multiply [tex]\frac{35}{8}[/tex] cups by 10.
So, [tex](\frac{35}{8}*10)cups= \frac{350}{8}cups= \frac{175}{4}cups= 43\frac{3}{4} cups[/tex]
Thus, [tex]43\frac{3}{4}[/tex] cups of cheese is needed to make 10 pizzas.
