Answer 1

Вот полностью решения

Answer 2

а) 7/16 + 1/4 = (7/16) + (4/16) = 11/16

б) 25/36 - 2/9 = (25/36) - (8/36) = 17/36

в) 7/12 - 5/24 = (7/12) - (10/24) = 14/24 = 7/12

г) 5/7 - 11/21 = (15/21) - (11/21) = 4/21

д) 1/6 + 5/18 = (3/18) + (5/18) = 8/18 = 4/9

е) 19/45 + 4/15 = (19/45) + (12/45) = 31/45

ж) 15/16 - 3/2 = (15/16) - (24/16) = -9/16

з) 7/15 + 1/3 = (7/15) + (5/15) = 12/15 = 4/5

и) 11/13 - 20/39 = (33/39) - (20/39) = 13/39

к) 3/50 + 18/25 = (3/50) + (36/50) = 39/50

л) 43/62 - 10/31 = (43/62) - (20/62) = 23/62 = 11/31

м) 29/64 + 3/8 = (29/64) + (24/64) = 53/64
