Taylor made 5 1⁄4 cups of iced tea. how many 10 ounce glasses can he fill to the brim with iced tea?

 
4

Explanation: 
Word problems like this are always a bit tricky to get to the bottom to. 
But to put it simply, this question is asking how many times can 10 oz be taken out of 5 1/4 cups. This is also shown as: 
5 1/4 cups ÷ 10 ounces 

First, make both numbers the same units. Since ounces are smaller, convert 5 1/4 cups into ounces. 
5 1/4 cups 
5 cups = 40 ounces 
1/4 cup = 2 ounces 
40 + 2 = 42 ounces. 
so now do this: 
42 ÷ 10 = 4.2 
So Taylor can fill 4 full glasses with iced tea.
