1) 1/3 - (+2/3) = 1/3 - 2/3 = -1/32)-2/5-(-3/5) = -2/5 + 3/5 = 1/53)5/6 - (-1/6) = 5/6 + 1/6 = 6/6 = 14) -3/7 - (+ 4/7) = -3/7 - 4/7 = -7/7 = -15) 5/8 - (-7/8) = 5/8 + 7/8 = 12/8 6) -1/9 - (+2/9) = -1/9 - 2/9 = - 3/9 = - 1/3

1) 1/3-(+2/3)=1/3-2/3=-1/3

2) -2/5-(-3/5)=-2/5+3/5=1/5

3) 5/6-(-1/6)=5/6+1/6=6/6=1

4) -3/7-(+4/7)=-3/7-4/7=-7/7=-1

5) 5/8-(-7/8)=5/8+7/8=12/8=3/2=1.5

6) -1/9-(+2/9)=-1/9-2/9=-3/9=-1/3
