1/3 + 1/2 = 5/6 - F
6 3/4 - 3 2/3 = 27/4 - 11/3 = 81/12 - 44/12 = 37/12 = 3 1/12 - I
3/4 - 1/6 = 9/12 - 2/12 = 7/12 - R
2/3 * 1 1/8 = 2/3 * 9/8 = 18/24 = 3/4 - O
1/4 * 4/5 = 4/20 = 1/5 - A
1 7/8 : 3/4 = 15/8 : 3/4 = 15/8 * 4/3 = 60/24 = 2 1/2 - N
5/8 : 15/22 = 5/8 * 22/15 = 110/120 = 11/12 - K
2 9/20 : 1 3/4 = 49/20 : 7/4 = 49/20 * 4/7 = 7/5 * 1/1 = 7/5 = 1 2/5 - E
1/3 + 1 3/4 = 4/12 + 1 9/12 = 4/12 + 21/12 = 25/12 = 2 1/12 - T
1 1/4 * 1 1/5 = 5/4 * 6/5 = 6/4 = 3/2 = 1 1/2 - N
