4 2/3 + 1 = 4 2/3 + 3/3 = 14/3 + 3/3 = 17/3 = 5 2/3;

5 3/8 + 5/8 = 43/8 + 5/8 = 48/8 = 6;

4 1/6 + 2 5/12 = 25/6 + 29/12 = 50/12 + 29/12 = 79/12 = 6 7/12;

9 1/6 + 1 2/5 = 55/6 + 7/5 = 275/30 + 42/30 = 317/30 = 10 17/30;

11 5/6 + 12 = 71/6 + 72/6 = 143/6 = 23 5/6;

9 4/5 + 1/5 = 49/5 + 1/5 = 50/5 = 10;

2 1/4 + 7 1/8 = 9/4 + 57/8 = 18/8 + 57/8 = 75/8 = 9 3/8;

10 5/8 + 7 1/12 = 85/8 + 85/12 = 255/24 + 170/24 = 425/24 = 17 17/24.
