Пошаговое объяснение:
4) - 2 целых 3/4 - ( - 4/7) = -11/4 + 4/7 = -77 + 16/ 28 = - 61/28 = - 2 целых 5/28
6) - 4 целых 11/12 - ( - 11/18) = - 59/12 + 11/18 = - 177 + 22 = 36 = - 155/36 = -4 целых 11/36
1) - 15 целых 3/4 - ( - 29 целых 3/5) = - 63/4 + 148/5 = - 315 + 592/20 = 277/20 = 13 целых 17/20
2) - 1 целая 7/9 - 3 целых 5/6 = - (( 1 + 3) + ( 7/9 + 5/6)) = -(4 + 29/18) = -( 4+1 целая 11/18) = - 5 целых 11/18
3) 16/21 - 5 целых 1/3 = 16/21 - 16\3 = 16 - 112/ 21 = - 96/21 = - 4 целых 4/7
