Amber made 5 3/4 pitchers of iced tea for her friends. They drank 2/3 of the iced tea.
How many pitchers of iced tea did they drink?
Do I subtract to get the answer?

whenever you see "of" think multiplication.
half of a dozen is 1/2 * 12 = 6
so, 2/3 of 5 3/4 = 2/3 * 23/4 = 46/12 = 23/6 = 3 5/6 
Thank you Steve for all your help! I have another question . I need to show 10/8 divided by 5/8 on a number line. I am completely lost!!! Please explain how to do this

Hmmm. Think of the 1/8 as a unit. You have 10 units divided by 5 units. The answer is 10/5 = 2
Mark off 5/8 on the line, mark off another 5/8 and note that 5/8 + 5/8 = 10/8. So, 10/8 ÷ 5/8 = 2.
arithmetically, 10/8 ÷ 5/8 = 10/8 x 8/5 = 80/40 = 2
