I found a similar problem. This is its table:
Volunteering
Student                 Time(hours)
Amy                              4 5/6
Beth                             6 1/2
Victor                           5 3/4
Cal                                5 2/3

Match each pair of students with the difference between how much time they spent volunteering.

Amy and Victor : 11/12 HOURS
Amy: 4 5/6 → 29/6 ; Victor: 5 3/4 → 23/4
29/6 - 23/4 = 29/6(2/2) - 23/4(3/3) = 58/12 - 69/12 = -11/12  

Cal and Beth : 5/6 HOURS
Cal : 5 2/3 → 17/3 ; Beth: 6 1/2 → 13/2
17/3 - 13/2 = 17/3(2/2) - 13/2(3/3) = 34/6 - 39/6 = -5/6

Beth and Victor : 3/4 HOURS
Beth: 6 1/2 → 13/2 ; Victor: 5 3/4 → 23/4
13/2 - 23/4 = 13/2(2/2) - 23/4(1/1) = 26/4 - 23/4 = 3/4

The first one is 5%
Second - 76 is 15 percent of what number? If we substitue "what number" in the question "76 is 15 percent of what number?" with 506.67, we get this sentence: 76 is 15 percent of 506.67. Since this statement is true, we know that our answer is correct.
Third - 25 percent (calculated percentage %) of what number equals 50? Answer: 200.
