Question

(2,06 : 1/60 - 14,84 : 7/60) * 1/6 -0,084 * 1/12 =



* = умножение

Answer 1

Пошаговое объяснение:

1) 2,06 : 1/60 = 206/100 * 60/1 = 206/5 * 3/1 = 218/5 = 43,6

2) 14,84 : 7/60 = 1484/100 * 60/7 = 212/5 * 3/1 =636/5 = 127,2

3) 43,6 - 127,2 = -83,6

4) -83,6 * 1/6 = -836/10 * 1/6 = -418/10 * 1/3 = -418/30 = -209/15 = -13 14/15

5) 0,084 * 1/12 = 84/1000 * 1/12 = 7/1000 * 1/1 = 7/1000

6) -13 14/15 - 7/1000 = -13 14000/15000 - 105/15000 = -13 14105/15000 = -13 2821/3000
