Пошаговое объяснение:

1) 9/5 = 1(4/5)

17/5 = 3(2/5)

31/8 = 3(7/8)

2) 2(4/15) = 34/15

4(15/21) = 99/21

8(3/7) = 59/7

3) 7/15 + 4/15 = 11/15

1/4 + 2/3 = 3/12 + 8/12 = 11/12

7(5/6) + 6(7/15) = 47/6 + 97/15 = 235/30 + 194/30 = 429/30 = 143

4) 9/11 - 7/11 = 2/11

5/9 - 3/12 = 20/36 - 9/36 = 11/36

5(3/8) - 3(5/6) = 43/8 - 23/6 = 129/24 - 92/24 = 37/24 = 1(13/24)

5) 7/9 × 8/10 = 56/90

5(1/7) × 4(4/6) = 36/7 × 28/6 = 24

7 × 1/3 = 6(3/3) × 1/3 = 21/3 × 1/3 = 7/3

6) 9 : 8/15 = 8(15/15) : 8/15 = 135/15 × 15/8 = 135/8 = 16(7/8)

8(1/3) : 3(4/7) = 25/3 : 25/7 = 25/3 × 7/25 = 7/3 = 2(1/3)
