Answer 1

Пошаговое объяснение:

1/5 - 1/6 = 6/30 - 5/30 = 1/30

3/4 - 1/3 = 9/12 - 4/12 = 5/12

7/9 - 2/11 = 77/99 - 18/99 = 59/99

3/4 - 4/9 = 27/36 - 16/36 = 11/36

7/8 - 5/12 = 21/24 - 10/24 = 11/24

11/12 - 11/18 = 33/36 - 22/36 = 11/36

Answer 2

Пошаговое объяснение:

1) 1/5 - 1/6 = (1 * 6 - 1 * 5)/30 = (6 - 5)/30 = 1/30

2) 3/4 - 1/3 = (3 * 3 - 4 * 1)/12 = (9 - 4)/12 = 5/12

3) 7/9 - 2/11 = ( 11 * 7 - 9 * 2)/99 = (77 - 18)/99 = 59/99

4) 3/4 - 4/9 = (9 * 3 - 4 * 4)/36 = (27 - 16)/36 = 11/36

5) 7/8 - 5/12 = (3 * 7 - 2 * 5)/48 = (21 - 10)/24 = 11/24

6) 11/12 - 11/18 = (3 * 11 - 2 *11)/36 =

= (33 - 22)/36 = 11/36
