Question

Owen ate three-eighths of a pizza for lunch. For dinner, he ate two-thirds of what was left from lunch. How much of the whole pizza did he eat for dinner?

Answer 1

After lunch, 5/8 of the original pizza remained.

At dinner, he consumed 2/3 of 5/8; in Math, 'OF' means multiply.

 

Owen ate (2/3)(5/8) = 5/12 of the original pizza for dinner.

Answer 2

Megan, eating 3/8 leaves 5/8 of the pizza. Since Owen ate 2/3 of the 5/8, he ate (2/3)(5/8) = 10/24 = 5/12 of the pizza for dinner.
