Answer 1

1) 16/25 + 14/15 = 1 43/75

2) (7/9 + 5/6) - (11/18 - 16/27) = 1 16/27 (т.к 7/9 + 5/6 = 29/18, а 11/18 - 16/27 = 1/54, соответственно 29/18 - 1/54 = 1 16/27).

Answer 2

1)16/25 + 14/15= 96/150 + 140/150 = 236/150 = 118/75
2) (7/9+5/6) - (11/ 18-16/27)= (14/18+15/18) - (11/18-16/27)= 29/18 - (11/18-16/27) = 29/18 - (33/54-32/54)= 29/18 - 1/54= 87/54 - 1/54= 86/54= 43/27
