Находим значение следующего выражения. Записываем решение. 

3 1/6 + 2 2/3 = 19/6 + 8/3 = 19/6 + 16/6 = (19 + 16)/6 = 35/6 = 5 5/6.

8 5/7 + 2 1/14 = 61/7 + 29/14 = 122/14 + 29/14 = (122 + 29)/14 = 151/14 = 10 11/14.

1 5/16 + 1 1/2 = 21/16 + 3/2 = 21/16 + 24/16 = (21 + 24)/16 = 45/16 = 2 13/16.

6 7/10 + 9 5/20 = 67/10 + 185/20 = 134/20 + 185/20 = 319/20 = 15 19/20.
