Let's start by finding out how much pizza was left after he ate 3/8 for lunch.
If he ate 3/8 of the pizza for lunch, then 5/8 of the pizza was left.
Next, if he ate 2/3 of what was left for lunch, he ate:
(2/3) * (5/8) = 10/24 = 5/12
So he ate 5/12 of the pizza for dinner.
Adding the portions eaten for lunch and dinner, he ate:
3/8 + 5/12 = 9/24 + 10/24 = 19/24
Therefore, he ate 19/24 of the whole pizza for dinner.
If he ate 3/8 of the pizza for lunch, then 5/8 of the pizza was left.
Next, if he ate 2/3 of what was left for lunch, he ate:
(2/3) * (5/8) = 10/24 = 5/12
So he ate 5/12 of the pizza for dinner.
Adding the portions eaten for lunch and dinner, he ate:
3/8 + 5/12 = 9/24 + 10/24 = 19/24
Therefore, he ate 19/24 of the whole pizza for dinner.
