[ 1/1 Equation]
    Work: Find the solution of equation 0.49/（50/Q+6.8） = 0.51/(40/Q+8.5) .
    Question type: Equation
    Solution:Original question:
     
49
100
 ÷ (50 ÷ Q +
34
5
) =
51
100
 ÷ (40 ÷ Q +

    The equation is reduced to :
     
98
5
 ÷ Q +
833
200
 =
51
2
 ÷ Q +
867
250
     Multiply both sides of the equation by: Q

2
 −
98
5

    Combine the items on the right of the equation:
     
697
1000
 Q =
59
10

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

1000
697
        = 59 ×
100
697

    We obtained :
      Q =
5900
697
    This is the solution of the equation.

    Convert the result to decimal form :
      Q = 8.464849
