Here's how you do it:

26. Divide the 24 gallons of juice by the volume of the juice inside each can:
24 divided by 3/8 = 24 x 8/3 = 64 cans
Ans: 64 cans are needed to make 24 gallons of juice.

27. For this question, you multiply the maximum number of people that could be seated in the theater by the fraction of 'full-ness' of the theater.
324 x 2/3 = 216 people
Ans: There are 216 people in the theater.

28. Subtraction is needed for this question (fell).
32 1/4 - 3/4 = 31 5/4 - 3/4 = 31 2/4 = 31 1/2 points
Ans: Its ending value was 31 1/2 points.

29. Again, for this sum, you subtract (pedaling away from hope minus pedaling after she turned around to go home) .
1 2/3 - 3/5 = 1 10/15 - 9/15 = 1 1/15 miles
Ans: She was 1 1/15 miles away from home.

30. Same concept as the last question.
5 3/10 - 1 1/5 = 5 3/10 - 1 2/10 = 4 1/10 miles
Ans: She was 4 1/10 miles away from home.

Hope this has helped you!
