100
15
100
(1 + X ) ÷ X ×
10
100
(1400 ÷ 800) = 0
    The equation is reduced to :
     
17
20
(1 + X ) ÷ X ×
10
100
(1400 ÷ 800) = 0
     Multiply both sides of the equation by: X
     
17
20
X (1 + X ) ×

X = 0 +
1
20

    Combine the items on the right of the equation:
     
4
5
X =
1
20

    The coefficient of the unknown number is reduced to 1 :
      X =
