Answer 1

2 7/9 - 1/3 = 2 7/9 - 3/9 = 2 4/9

3 4/5 - 2/3 = 3 12/15 - 10/15 = 3 2/15

4 5/6 - 2 1/3 = 4 5/6 - 2 2/6 = 2 3/6 = 2 1/2

6 4/5 - 2 3/8 = 6 32/40 - 2 15/40 = 3 17/40

9 1/2 - 4 3/8 = 9 4/8 - 4 3/8 = 5 1/8

8 19/20 - 5 7/10 = 8 19/20 - 5 14/20 = 3 5/20 = 3 1/4

Answer 2

Пошаговое объяснение:

1) 2  7/9-1/3= 25/9-1/3=25/9-3/9=22/9= 2 4/9

2)3  4/5-2/3= 19/5-2/3=57/15-10/15=67/15=4 7/15

3)4  5/6-2  1/3= 29/6-7/3=29/6-17/6=12/6=2

4)6  4/5-2  3/8= 34/5- 19/8= 272/40-95/40=177/40=4 17/40

5)9  1/1-4  3/8=  10- 3/8= 9 5/8

6)8  19/20-5  7/10=  179/20-57/10= 179/20-114/20=65/20=3 5/20= 3 1/4
