4-27/39=3 39/39-27/39=3 12/39

Answer 3

А) 7 - 2/23 = 161/23 - 2/23 = (161 - 2) / 23 = 159/23

Б) 5 - 4/19 = 95/19 - 4/19 = (95 - 4) / 19 = 91/19

В) 15 - 17/43 = 645/43 - 17/43 = (645 - 17) / 43 = 628/43

Г) 8 - 12/37 = 296/37 - 12/37 = (296 - 12) / 37 = 284/37

Д) 11 - 7/29 = 319/29 - 7/29 = (319 - 7) / 29 = 312/29

Е) 4 - 27/39 = 156/39 - 27/39 = (156 - 27) / 39 = 129/39 = 43/13

Таким образом:

А) 7 - 2/23 = 159/23

Б) 5 - 4/19 = 91/19

В) 15 - 17/43 = 628/43

Г) 8 - 12/37 = 284/37

Д) 11 - 7/29 = 312/29

Е) 4 - 27/39 = 43/13
