Answer 1

1) -4+5=1
2) -4-5= -9
3) -4*5= -20
4) -4:5= -0,8

1) -12+(-3)=-15
2) -12-(-3) = -9
3) -12*(-3) = -36
4) -12:(-3)=-4

1) 7+(-0.2) =6.8
2) 7-(-0.2)=7.2
3) 7*(-0.2)= -1.4
4) 7:(-0.2)= -35

1) -3.6+(-2.5) = -6.1
2) -3.6-(-2.5) = -0.9
3) -3.6*(-2.5) = 9
4) -3.6:(-2.5) = 1.44

1) -2/7 + 3/14 = 1/14
2)-2/7 - 3/14 = 7/14≈ 1/2
3) -2/7 * 3/14 = -6/98
4) -2/7 : 3/14 = -28/21

1) 1. 1/2 + (-1. 1/4) =-2/4
2) 1.1/2 -(-1.1/4) = 8/4 ≈2
3) 1.1/2 *(-1.1/4) = -15/8 ≈ -1.3/8
4) 1.1/2 : (-1.1/4) =-12/10≈ -1.1/5
