Answer 1

Ответ:

1. (14, 6 * 2, 8 - 4, 94) : (57, 6 : 18 + 2, 8) = 5, 99

1) 14, 6 * 2, 8 = 40, 88

2) 40, 88 - 4, 94 = 35, 94

3) 57, 6 : 18 = 3, 2

4) 3, 2 + 2, 8 = 6

5) 35, 94 : 6 = 5, 99

2. (55, 08 : 1, 8 - 4, 056 : 0, 52) * 6, 5 - 93, 78 =

54, 42

1) 55, 08 : 1, 8 = 5508 / 100 : 18 / 10 = 5508 / 100 * 10 / 18 = (306 * 18 * 10) / (10 * 10 * 18) = 306 / 10 = 30,6

2) 4, 056 : 0, 52 = 7, 8

3) 30, 6 - 7, 8 = 22, 8

4) 22, 8 * 6, 5 = 148, 2.

5) 148,2 - 93,78 = 54,42.
