Пошаговое объяснение:
1.
5 7/8 - 2 2/3 + 4 5/6 = 8 1/24
1) 5 7/8 - 2 2/3 = 5 21/24 - 2 16/24 = 3 5/24
2) 3 5/24 + 4 5/6 = 3 5/25 + 4 20/24 = 7 25/24 = 8 1/24
2.
6 8/15 + 4 5/18 - 3,6 = 7 7/45
1) 6 8/15 + 4 5/18 = 6 48/90 + 4 20/90 = 10 68/90 = 10 34/45
2) 10 34/45 - 3,6 = 10 34/45 - 3 6/10 = 10 34/45 - 3 3/5 =
= 10 34/45 - 3 27/45 = 7 7/45
3.
(43 7/18 - 5 2/9) - 12 8/27 = 25 47/54
1) 43 7/18 - 5 2/9 = 43 7/18 - 5 4/18 = 38 3/18 = 38 1/6
2) 38 1/6 - 12 8/27 = 38 9/54 - 12 16/54 = 37 63/54 -
- 12 16/54 = 25 47/54
4.
(31 - 14 7/15) - (27 2/3 - 19 3/4) = 7 37/60
1) 31 - 14 7/15 = 30 15/15 - 14 7/15 = 16 8/15
2) 27 2/3 - 19 3/4 = 27 8/12 - 19 9/12 = 26 20/12 - 19 9/12 = 7 11/12
3) 16 8/15 - 8 11/12 = 16 32/60 - 8 55/60 = 15 92/60 - 8 55/60 =
= 7 37/60
