Answer 1

Пошаговое объяснение:

№1

59 25/64 - (32 3/16 + 4 1/64) =

59 25/64 - 32 3/16 - 4 1/64 = 55 24/64 - 32 3/16 = 55 6/16 - 32 3/16 = 23 3/16

№2

32 2/45 + (20 5/9 - 18 4/5) =

32 2/45 + (20 25/45 - 18 36/45) =

32 2/45 + (19 70/45 - 18 36/45) =

32 2/45 + 1 34/45 = 33 36/45 = 33 4/5

№3

37 29/36 - (4 5/18 + 1 31/48) =

37 116/144 - (4 40/144 + 1 93/144) =

37 116/144 - 5 133/144 = 36 260/144 - 5 133/144 =

31 127/144

№4

(40 61/80 - 7 17/20) + 25 3/40 =

40 61/80 - 7 68/80 + 25 6/80 =

39 141/80 - 7 68/80 + 25 6/80 =

32 73/80 + 25 6/80 = 57 79/80
