Answer:

Whatever is in the parenthesis.

Step-by-step explanation:

A good way to remember what operation you should do first in these kinds of problems is: PEMDAS.

Each letter in PEMDAS stands for a function in problems, and it gives the order that you should do them in.

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

1. Parenthesis; always comes first.

2. Exponents; always comes second.

3. Multiplication/Division; it does NOT matter which one you do first out of these two.

4. Multiplication/Division; whatever you didn't do on #3

5. Addition/Subtraction; it does NOT matter which one you do first out of these two.

6. Addition/Subtraction; whatever you didn't do on #5.

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.
