Пошаговое объяснение:

1.

1) 5 - 3/11 = 4. 11/11 - 3/11 =

4. 8/11

2) 4. 8/11 : 13 = 52/11 * 1/13 = 4/11 * 1/1 = 4/11

3) 4/11 + 1/2 = 8/22 + 11/22 = 19/22.

2.

1) 7/12 + 1/2 = 7/12 + 6/12 = 13/12

2) 13/24 : 13/12 = 13/24 * 12/13 = 12/24 = 1/2

3) 1/2 - 1/4 = 2/4 - 1/4 = 1/4.

3.

1) 3/5 : 9/10 = 3/5 * 10/9 =

1/1 * 2/3 = 2/3

2) 3/5 * 8/9 = 24/45 = 8/15

3) 2/3 - 8/15 = 10/15 - 8/15 = 2/15.
