[ 1/1 Equation]
    Work: Find the solution of equation 2000:30 = x:45 .
    Question type: Equation
    Solution:Original question:
     2000 ÷ 30 = x ÷ 45
     Left side of the equation =
200
3
    The equation is transformed into :
     
200
3
= x ÷ 45

    Transposition :
      -
1
45
x = -
200
3

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
200
3
=
1
45
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 :
     
1
45
x =
200
3

    The coefficient of the unknown number is reduced to 1 :
      x =
200
3
÷
1
45
        =
200
3
× 45
        = 200 × 15

    We obtained :
      x = 3000
    This is the solution of the equation.
