[ 1/1 Equation]
    Work: Find the solution of equation (1.5+y)/(1+2.33+1.5+y) = 0.3 .
    Question type: Equation
    Solution:Original question:
     (
3
2
 + y ) ÷ (1 +
233
100
 +
3
2
 + y ) =
3
10
     Multiply both sides of the equation by:(1 +
233
100
 +
3
2
 + y )
     (
3
2
 + y ) =

 y = -
51
1000

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

    This is the solution of the equation.

    Convert the result to decimal form :
      y = - 0.072857
