Answer 1

5 + 2 целых 3/8 = 40/8 + 19/8 = 59/8 = 7,375

4 целых 8/11 + 2 целых 5/11 = 52/8 + 27/8 = 79/8 = 9,875

10 целых 3/4 + 7 = 43/4 + 28/4 = 71/4 = 17,75

2 целых 1/12 + 5/6 = 25/12 + 10/12 = 35/12 = 2 целых 11/12

6 + 4 целых 5/7 = 42/7 + 33/7 = 75/7 = 10 целых 5/7

9 целых 1/4 + 5 целых 5/7 = 37/4 + 40/7 = 259/28 + 160/28 = 419/28 = 14 целых 27/28
