60+(12-9-350: 72). 9.8(42:3+21): 7​

Answer 1

Пошаговое объяснение:

60 + (12 - 9 - 350 : 72) = 62 139/175

1) 350 : 72 = 350/72 = 36/175

2) 12 - 9 = 3

3) 3 - 36/175 = 2 175/175 - 36/175 = 2 139/175

4) 60 + 2 139/175 = 62 139/175

9,8(42 : 3 + 21) : 7 = 49

1) 42 : 3 = 14

2) 14 + 21 = 35

3) 9,8 * 35 = 343

4) 343 : 7 = 49
