[ 1/1 Equation]
    Work: Find the solution of equation 10/X = (2/7)/0.8 .
    Question type: Equation
    Solution:Original question:
     10 ÷ X = (2 ÷ 7) ÷
4
5
     Multiply both sides of the equation by: X
     10 = (2 ÷ 7) ÷
4
5
× X
    Remove a bracket on the right of the equation::
     10 = 2 ÷ 7 ÷
4
5
× X
    The equation is reduced to :
     10 =
5
14
X

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
5
14
X = 10

    The coefficient of the unknown number is reduced to 1 :
      X = 10 ÷
5
14
        = 10 ×
14
5
        = 2 × 14

    We obtained :
      X = 28
    This is the solution of the equation.
