Пошаговое объяснение:

5 13/55 +2 13/14 = 5 182/770 + 2 715/770 = 7 897 /770 = 8 127/770

4 5/6 + 3 3/10 = 4 25/30 + 3 9/30 = 7 34/30 = 8 4/30 = 8 2/15

19/42 - (5/42 + 1/5) = 19/42 - 5/42 - 1/5 = 14/42 - 1/5 = 1/3 - 1/5 = 5/15 - 3/15 = 2/15

3 7/8 + 2 5/12 = 3 21/24 + 2 10/24 = 5 31/24 = 6 7/24

4 9/14 + 3 4/21 = 4 27/42 + 3 8/42 = 7 35/24 = 8 11/244

1 +2 5/16 = 3 5/16

5 2/15 + 3 5/12= 5 16/120 + 3 50/120 = 8 66/120 = 8 11/20

2 1/8 + 8 1/12 = 2 3/24 + 8 2/24 = 10 5/24

6 13/15 + 3 7/12 = 6 52/60 + 3 35/60 = 9 87/60 = 10 27/60 = 10 9/20

5 5/6 + 1 3/4 = 5 10/12 + 1 9/12 = 6 19/12 = 7 7/12
