Answer 1

Пошаговое объяснение:

1)

10 23/25 - 3 7/10 - 2 1/5 =

10 46/50 - 3 35/50 - 2 10/50 =

(10-3-2) + (46-35-10)/50 =

5 + 1/50 = 5 1/50

2)

26 - (3 1/6 + 2 1/4) = 26 - (3 2/12 + 2 3/12) =

26 - 5 5/12 = 25 12/12 - 5 5/12 = 20 7/12

3)

7 5/6 + (7 3/5 - 1 7/10) =

7 25/30 + (7 18/30 - 1 21/30) =

7 25/30 + (6 48/30 - 1 21/30) =

7 25/30 + 5 27/30 = 12 52/30 =

12 26/15 = 13 11/15

4)

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

2 18/30 + 2 5/30 - 1 20/30 =

(2+2-1) + (18+5-20)/30 = 3 3/30 = 3 1/10
