Question

3/5-4/5= 2/7-(-3/7)= -1/9-(5/9)= 6/7-8/7= 3/9-(-2/9)= -5/8-(-3/8)= -1/12-(-5/12)= 2/15-7/15= 4/9-5/9=

Answer 1

3/5-4/5=
2/7-(-3/7)=2/7+3/7=5/7
-1/9-(5/9)=-1/9-5/9=-6/9=-2/3
6/7-8/7==-2/7
3/9-(-2/9)=3/9+2/9=5/9
-5/8-(-3/8)=-5/8+3/8=-2/8=-1/4
-1/12-(-5/12)=-1/12+5/12=4/12=1/3
2/15-7/15=-2/15
4/9-5/9=-1/9

Answer 2

Let's solve each of these equations step by step:

1. 3/5 - 4/5: (3/5) - (4/5) = (3 - 4)/5 = -1/5

2. 2/7 - (-3/7): (2/7) - (-3/7) = (2/7) + (3/7) = (2 + 3)/7 = 5/7

3. -1/9 - (5/9): (-1/9) - (5/9) = (-1 - 5)/9 = -6/9 = -2/3

4. 6/7 - 8/7: (6/7) - (8/7) = (6 - 8)/7 = -2/7

5. 3/9 - (-2/9): (3/9) - (-2/9) = (3/9) + (2/9) = (3 + 2)/9 = 5/9

6. -5/8 - (-3/8): (-5/8) - (-3/8) = (-5/8) + (3/8) = (-5 + 3)/8 = -2/8 = -1/4

7. -1/12 - (-5/12): (-1/12) - (-5/12) = (-1/12) + (5/12) = (-1 + 5)/12 = 4/12 = 1/3

8. 2/15 - 7/15: (2/15) - (7/15) = (2 - 7)/15 = -5/15 = -1/3

9. 4/9 - 5/9: (4/9) - (5/9) = (4 - 5)/9 = -1/9

So, the solutions to the equations are:

1. 3/5 - 4/5 = -1/5
2. 2/7 - (-3/7) = 5/7
3. -1/9 - (5/9) = -2/3
4. 6/7 - 8/7 = -2/7
5. 3/9 - (-2/9) = 5/9
6. -5/8 - (-3/8) = -1/4
7. -1/12 - (-5/12) = 1/3
8. 2/15 - 7/15 = -1/3
9. 4/9 - 5/9 = -1/9
