[(1-1/4-5/12)^3:(1/3-1/2)^2-(3/2)^-2]:{[(-4)^-3:(1/8-3/4)-2/5]^2x(-4/3)^3}
  =[(1-1/4-5/12)^3÷(1/3-1/2)^2-(3/2)^(-2)]÷{[(-4)^(-3)÷(1/8-3/4)-2/5]^2x(-4/3)^3}
  =[(1/3)^3÷(-1/6)^2-(2/3)^2]÷{[(-1/4)^3÷(-5/8)-2/5]^2x(-4/3)^3}
  =[(1/27)÷(1/36)-(4/9)]÷{[(-1/64)÷(-5/8)-2/5]^2x(-64/27)}
  =[(1/27)x36)-(4/9)]÷{[(-1/64)x(-8/5)-2/5]^2x(-64/27)}
  =[(4/3)-(4/9)]÷{[(1/40)-2/5]^2x(-64/27)}
  =[8/9]÷{[-3/8]^2x(-64/27)}
  =[8/9]÷{[9/64]x(-64/27)}
  =[8/9]÷{-1/3}
  =-(8/9)x3
  =-8/3
  =-二又三分之二.
