[ 1/1 Equation]
    Work: Find the solution of equation sprt(7%*(1-7%)*15%) = 0 .
    Question type: Equation
    Solution:Original question:
      s (
7
100
(1 −
7
100
) ×
15

) = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = s ×

 s
    The equation is transformed into :
     
1953
200000
 s = 0

    The coefficient of the unknown number is reduced to 1 :
      s = 0 ÷
1953
200000
        = 0 ×
200000
1953

    We obtained :
      s = 0
    This is the solution of the equation.
