Answer 1

1. Put in ascending order
3/7, -6/7, 1/7, -1/2, 2/7
-6/7, -1/2, 1/7, 2/7, 3/7

2. 1/3 + (-5/6) + (-1/2)=2/6-5/6-3/6=-4/6=-2/3

3. -1/2 - (-5/8)=-4/8+5/8=1/8

4. (-3)(-6) + (4)(-2)=18-8=10

5. (12)(-7) + (2)(-3)=-84-6=-90

6. (-3)to 3rd power - (-8)(-2)=-27-16=-43

7. (-8)to the 2nd power - 5 to the second power=64+25=89

8. (-6)to the 2nd power - 4 to the second power=36+16=42

9. 9 to the 2nd power - (-6) to the 2nd power=81-36=45

Answer 2

1. Put in ascending order
3/7, -6/7, 1/7, -1/2, 2/7

-6/7, -1/2, 1/7,2/7,3/7

2. 1/3 + (-5/6) + (-1/2) = 2/6-5/6-3/6= - 4/6= - 2/3

3. -1/2 - (-5/8)=-4/8+5/8 = 1/8

4. (-3)(-6) + (4)(-2)=18-8=10

5. (12)(-7) + (2)(-3) = -84-6 = -90

6. (-3)to 3rd power - (-8)(-2)=-27-16=-43

7. (-8)to the 2nd power - 5 to the second power = 64+25 = 89

8. (-6)to the 2nd power - 4 to the second power = 36+16 = 42

9. 9 to the 2nd power - (-6) to the 2nd power = 81-36= 45

Answer 3

1.order:-6/7,-1/2,1/7,2/7,3/7
2.equals....=2/6-5/6-3/6=-6/6=-1
3.equ...=-4/8+5/8=1/8
4.eq....=3*6-4*2=18-8=10
5.........=-12*7-2*3=-84-6=-90
6.........=(-3)^3-(8*2)=-27-16=-43
7.........=(-8)^2-5^2=64-25=39
8.........=(-6)^2-4^2=36-16=20
9.........=9^2-(-6)^2=81-36=45
