Answer 1

Ответ:

1)−12+15−6+12=9

2)−13−15+9−17=−36

3)−4.7+0.6−0.9+1.8=−3.2

Answer 2

1) -12 + 15 - 6 + 12 = 9

2) -13 - 15 + 9 - 17 = -36

3) -4.7 + 0.6 - 0.9 + 1.8 = -3.2

4) -3/4 + 4/3/8 - 1/2 + 7/3/4 = -0.75

5) 9.27 - 8/7/9 - 7.27 = 0.03

6) 0.75 - 3/4 - 5.7 - 4/3/10 = -6.41

Answer 3

1) -12 + 15 - 6 + 12 = 9 2) -13 - 15 + 9 - 17 = -36 3) -4.7 + 0.6 - 0.9 + 1.8 = -3.2 4) -3/1/4 + 4/3/8 - 1/2 + 7/3/4 = -3/4 5) 9.27 - 8/7/9 - 7.27 = 0.73 6) 0.75 - 3/4 - 5.7 - 4/3/10 = -7.25
