  1. (1988×1996+1997+1985)/(1997×1996−1995×1996)
    =(1988×1996+1997+1985)/(1997×1996−1995×1996)
    =1996×(1988+1985)/(1997−1995)+1997
    =1996×3,99399…+1997
    =7972,006009+1997
    =9969,006009
     

  2. (1988 × 1996+1997+1985)/(1997 × 1996-1995 × 1996)
    =(1988 × 1996+1997+1985)/(1997 × 1996-1995 × 1996)
    =1996 × (1988 + 1985)/(1997 -1995) +1997
    =1996 × 3,99399… +1997
    =7972,006009 + 1997
    =9969,006009
