[ 1/1 Equation]
    Work: Find the solution of equation u/(12-u) = 4/15 .
    Question type: Equation
    Solution:Original question:
      u ÷ (12 u ) = 4 ÷ 15
     Multiply both sides of the equation by:(12 u )
      u = 4 ÷ 15 × (12 u )
    Remove a bracket on the right of the equation::
      u = 4 ÷ 15 × 124 ÷ 15 × u
    The equation is reduced to :
      u =
16
5
4
15
u

    Transposition :
      u +
4
15
u =
16
5

    Combine the items on the left of the equation:
     
19
15
u =
16
5

    The coefficient of the unknown number is reduced to 1 :
      u =
16
5
÷

19
        = 16 ×

19

    We obtained :
      u =
48
19
    This is the solution of the equation.

    Convert the result to decimal form :
      u = 2.526316
