Answer:
3 cups of sugar.
Explanation:
Han drinks 3/4 of a cup of sugar each day when she drinks iced tea. She drinks 3 gallons, and each contains 3/4. If each contains only 3/4, we will have to multiply 3/4 by 3 gallons to find our answer to this question.

So, now we will have to multiply 3/4 by the number 3.
×
=

12/4 is equal to 3, so the answer is 3.
