Question

You have 3 1/3 pizza's leftover from a party, now your brother is still hungry and he eats 4/7 of what is left. How many whole pizza's did he eat?

Answer 1

1 whole pizza

Explanation:

3 ⅓ = 10/3

4/7 of 3⅓

4/7 × 10/3

40/21

1 19/21

Answer 2

Multiply what is left by how much he ate:

3 1/3 x 4/7

Rewrite 3 1/3 as an improper fraction:

10/3

Now multiply:

10/3 x 4/7 = 40/21

Rewrite as a mixed number:

40/21 = 1 19/21 Pizzas

He ate 1 whole pizza
