Question

Portia and her friends bought 8 pizzas. They initially ate one-third of the pizzas. Later

they ate two-fifths of the pizza that remained. They then ate three whole pizzas.
What fraction of a pizza remains?

Answer 1

⅕

Explanation:

Ate ⅓, so 1 - ⅓ = ⅔ left

⅔ of 8 = ⅔ × 8 = 16/3

Ate ⅖, so 1 - ⅖ = ⅗ left

⅗ of 16/3 = ⅗ × 16/3 = 16/5 = 3⅕

Ate 3 more, so

3⅕ - 3 = ⅕ left
