We start out with 1/2 pitcher. They shared 3/4 of that amount that was in the pitcher. 3/4 x 1/2 = 3/8 In total, they shared 3/8 of a pitcher of iced tea. It says they shared it equally, meaning each of them got half of the 3/8. 1/2 x 3/8 = 3/16 That gives us the answer to: a) They each drank 3/16 of a pitcher of iced tea.
So, they shared 3/8 of the pitcher. Meaning they drank 3/8 of it. Meaning 5/8 of it is still left in the pitcher. That gives us the answer to: b) 5/8 of a pitcher of iced tea was left over.
