3) -2-[-1/6-(2+2/3)]-(-1/2)

4) 4/7-{-1/3+[-1/4+(2-1/2+1/3)]-1}

5) -1/2-(-1/2)-{-1/2-[-1/2-(-1/2)]}

Answer 1

-1/3-(-7/5)-1/4 > -1/3+7/5-1/4 > -20-105-5/60 > -130/60 > -13/10

(-2/5-3)-(-4/3)+(1-1/2)  > -17/5+4/3+1/2 > -47/30

-2-[1/6-(2+2/3)]-[1+1/2] > -2-[1/6-8/3]-1/2 > -2-15/6-1/2 > -30/6 >-5

4/7-{-1/3+[-1/4+11/6)]-1} > 4/7-{-1/3+2/3-1} > 4/7 - {-2/3} > 4/7+2/3 > 26/21

-1/2+1/2-{-1/2-[-1/2-(-1/2)]}  > -1/2 + 1/2 - {-1/2-[-1/2+1/2]} > -1/2 + 1/2-{-1/2} > -1/2 + 1 >  

> 1/2
