1 ) 5/9 + ( -8/13 ) + ( -4/15 ) + 9/20

  • = 5/9 - 8/13 - 4/15 + 9/20
  • = 5/9 + 9/20 - 8/13 - 4/15
  • = 0.5 + 0.45 - 0.61 - 0.26
  • = 0.95 - 0.87
  • = 0.08 ( approx )

2 ) -6/7 x 35/27 x 2/3 x ( -9/40 )

  • = - 0.85 x 1.29 x 0.6 x ( - 0.225 )
  • = - 1.0965 x ( - 0.135 )
  • = 0.1480275 ( approx )
