Пошаговое объяснение:
1.
1) 2 - 1/3 = 1. 3/3 - 1/3 = 1. 2/3
2) 3 : 1. 2/3 = 3 : 5/3 = 3 * 3/5 = 9/5 = 1. 4/5
3) 1/5 + 1. 4/5 = 1. 5/5 = 2
2.
1) 1 - 1/2 = 2/2 - 1/2 = 1/2
2) 1 : 1/2 = 1 * 2/1 = 2/1 = 2
3) 3 - 2 = 1
3.
1) 1 - 4/5 = 5/5 - 4/5 = 1/5
2) 1 : 1/5 = 1 * 5/1 = 5/1 = 5
3) 7 - 5 = 2
4.
1) 1 - 3/4 = 4/4 - 3/4 = 1/4
2) 2 : 1/4 = 2 * 4/1 = 8/1 = 8
3) 9 - 8 = 1
