1) -(2. 1/2 * 0,24 - 15/29) = -(5/2 * 24/100 - 15/29) = -(1/1 * 12/20 - 15/29) = -(12/20 - 15/29) = -(3/5 - 15/29) = -3/5 + 15/29 = -87/145 + 75/145 = -12/145

2) 5,45 + 1. 4/45 = 5. 45/100 + 1. 4/45 = 5. 9/20 + 1. 4/45 = 5. 81/180 + 1. 16/180 = 6. 97/180

3) 6. 97/180 - 6. 1/18 = 6. 97/180 - 6. 10/180 = 87/180 = 29/60

4) 36,05 : 10,3 = 3,5

5) -12/145 * 29/60 = -1/5 * 1/5 = -1/25 = -0,04

6) -0,04 + 3,5 = 3,46 или 3. 46/100 = 3. 23/50

Ответ:

3,46
