this problem is a math riddle where in you need to solve a series of questions to get the answer. the following are the answers with their corresponding letter:

8 = n = 9 1/8

15 = t = 12 4/9

14 = i = 12 7/15

10 = h = 8 7/12

12 = c = 14 1/18

6 = l = 14 1/10

5 = u = 6 3/8

7 = d = 6 ½

2 = e = 14 3/10

4 = o = 8 23/24
