Answer 1

Ответ:

а) 1/2 / (2/3) = (1/2) * (3/2) = 3/4

1/6 / (2/7) = (1/6) * (7/2) = 7/72

б) 2/5 / (3/7) = (2/5) * (7/3) = 14/15

3/4 + 15/16 = (12/16) + (15/16) = 27/16

у * 2/9 + 1/4 = у * (2/9) + 1/4

11/18 + 11/12 = (22/36) + (33/36) = 55/36

3/11 * 1/3 = 3/33 = 1/11

49/68 + 21/34 = (147/204) + (119/204) = 266/204 = 133/102
