Answer 1

Пошаговое объяснение:

№1

1) 2 1/5 - 1 5/6 = 2 6/30 - 1 25/30 = 1 36/30 - 1 25/30 = 11/30

2) 4 29/60 - 11/30 = 4 29/60 - 22/60 = 4 7/60

3) 7 1/12 - 4 7/60 = 7 5/60 - 4 7/60 = 6 65/60 - 4 7/60 = 2 58/60 = 2 29/30

4) 5 7/15 - 2 29/30 = 5 14/30 - 2 29/30 = 4 44/30 - 2 29/30 = 2 15/30 = 2 1/2

№2

1) 14 7/24 - 10 31/48 = 14 14/48 - 10 31/48 = 13 62/48 - 10 31/48 = 3 31/48

2) 2 3/4 - 1 7/12 = 2 9/12 - 1 7/12 = 1 2/12 = 1 1/6

3) 3 31/48 - 1 1/6 = 3 31/48 - 1 8/48 = 2 23/48

4) 6 13/24 - 2 23/48 = 6 26/48 - 2 23/48 = 4 3/48 = 4 1/16

5) 4 1/16 - 1 1/16 = 3
