[ 1/1 Equation]
    Work: Find the solution of equation (0.001+y)/(0.3-y)(0.01-y) = 3.2 .
    Question type: Equation
    Solution:Original question:
     (
1
1000
+ y ) ÷ (
3
10
y ) × (
1
100
y ) =
16
5
     Multiply both sides of the equation by:(
3
10
y )
     (
1
1000
+ y )(
1
100
y ) =
16

    Remove a bracket on the right of the equation::
     
1
1000
(
1
100
y ) + y (
1
100
y ) =
16
