[ 1/1 Equation]
    Work: Find the solution of equation 99.7*(1+r) = 30.4/r .
    Question type: Equation
    Solution:Original question:
     
997
10
(1 + r ) =
152
5
÷ r
     Multiply both sides of the equation by: r
     
997
10
(1 + r ) r =
152
5
    Remove a bracket on the left of the equation::
     
997
10
× 1 r +
997
10
r r =
152
5
    The equation is reduced to :
     
997
10
r +
997
10
r r =
152
5
