Question

Stanley ordered 2 pizzas cut into eighths. if he ate 5/8 of a pizza, how much was left?

Answer 1

There was 11/8 of pizza left after Stanley ate.

2 x 8/8 = 16/8
16/8 - 5/8 = 11/8

Answer 2

Answer:  The required quantity of pizza that was left is $\dfrac{11}{8}.$

Step-by-step explanation:  Given that Stanley ordered 2 pizzas cut into eighths and the ate $\dfrac{5}{8}$ of a pizza.

We are to find the quantity of the pizza that was left.

According to the given information, we have

number of pizzas, n = 2

and

the fraction of the pizza ate by Stanley is

$f=\dfrac{5}{8}.$

Therefore, the quantity of pizza that was left is given by

$p_l=n-f=2-\dfrac{5}{8}=\dfrac{2\times8-5}{8}=\dfrac{16-5}{8}=\dfrac{11}{8}.$

Thus, the required quantity of pizza that was left is $\dfrac{11}{8}.$
