Answer 1

Пошаговое объяснение:

1) 13/18 - 7/27 = 39-14/54= 25/54

2) 25/54 : 5/12 = 25/54 * 12/5 = 5/54 * 12 = 5/9 * 2 = 10/9

1) 3 * 5/13 = 15/13

2) 7/9 * 2/5 = 14/45

3) 7/12 * 4/21 = 28/252 = 1/9

4) 8 : 4/9 = 8 * 9 / 1*4 = 72/4 = 18

5) 7/12 - 3/20 = 35/60 - 9/60 = 26/60 = 13/30

6) 1 - 2/11 = 11/11 - 2/11 = 9/11
