Для варианта 2 необходимо выполнить следующие вычисления:
1) 1 2/5 + 1/3 = 1 6/15 + 5/15 = 1 11/15
2) 3 2/7 + 2/9 = 3 18/63 + 14/63 = 3 32/63
3) 1 3/2 + 1/4 = 1 6/8 + 2/8 = 1 8/8 = 2
4) 2 1/1 + 1/5 = 3 1/5
5) 1 1/25 + 1/10 = 1 2/50 + 5/50 = 1 7/50
6) 4 2/21 + 1/15 = 4 10/105 + 7/105 = 4 17/105
7) 2 5/27 + 1/18 = 2 10/54 + 3/54 = 2 13/54
8) 1 1/2 + 1/3 = 1 3/6 + 2/6 = 1 5/6
9) 1 13/50 + 1/25 = 1 13/50 + 2/50 = 1 15/50 = 1 3/10
10) 3 7/33 + 1/66 = 3 14/66 + 1/66 = 3 15/66 = 3 5/22
11) 3 3/100 + 1/25 = 3 3/100 + 4/100 = 3 7/100
12) 2 2/13 + 1/11 = 2 22/143 + 13/143 = 2 35/143
13) 1 1/20 + 1/300 = 1 15/300 + 1/300 = 1 16/300 = 1 4/75
14) 7 4/5 + 1/3 = 7 12/15 + 5/15 = 7 17/15 = 8 2/15
15) 1 10/20 + 1/2 = 1 1/2 + 1/2 = 2
16) 4 5/8 + 1/10 = 4 25/40 + 4/40 = 4 29/40
Итоговые значения:
1 11/15, 3 32/63, 2, 3 1/5, 1 7/50, 4 17/105, 2 13/54, 1 5/6, 1 3/10, 3 5/22, 3 7/100, 2 35/143, 1 4/75, 8 2/15, 2, 4 29/40
