Answer 2

Абдырахман, күткөнчө сенеге көмек көрсөтүм:

а)

1. 8/15 + 3/15 = (8 + 3) / 15 = 11/15
2. 13/28 - 5/28 = (13 - 5) / 28 = 8/28 = 2/7

б)

1. 12/27 + 14/21 = (4/9 + 2/3) = (4/9 + 6/9) = 10/9 = 1 1/9
2. 14/24 - 15/40 = (7/12 - 3/8) = (14/24 - 9/24) = 5/24

в)

1. 2 3/11 + 31/6 = (2 + 3/11 + 31/6) = (22/11 + 33/11) = 55/11 = 5
2. 41/5 - 11/15 = (41/5 - 9/15) = (123/15 - 9/15) = 114/15 = 38/5 = 7 3/5
