7 5/8 + 5 5/8 = 12 10/8 = 13 1/4

13 1/4 = 13 4/16

13 4/16 - 11 5/16 = 1 15/16

7 5/8 + 5 5/8 - 11 5/16
= 12 10/8 - 11 5/16
= 12 (2/2)(10/8) - 11 5/16
= 12 20/16 - 11 5/16
= 1 15/16

7 + 5 - 11 + 10/16 + 10/16 - 5/16
1 + 15/16

(7 5/8 + 5 5/8) - 11 5/16
13 2/8 - 11 5/16
13 4/16 - 11 5/16 = 1 15/16
