[ 1/1 Equation]
    Work: Find the solution of equation 500(1+m%)×1000(1+m/2%) = 660000 .
    Question type: Equation
    Solution:Original question:
     500(1 + m ) × 1000(1 + m ÷
2
100
) = 660000
     Left side of the equation = 500000(1 + m )(1 + m ÷
2
100
)
    The equation is transformed into :
     500000(1 + m )(1 + m ÷
2
100
) = 660000
    Remove the bracket on the left of the equation:
     Left side of the equation = 500000 × 1(1 + m ÷
2
100
) + 500000 m (1 + m ÷
2
100
)
                                             = 500000(1 + m ÷
2
100
) + 500000 m (1 + m ÷
2
100
)
                                             = 500000 × 1 + 500000 m ÷
2
100
+ 500000 m (1 + m ÷
2
100
)
                                             = 500000 + 25000000 m + 500000 m (1 + m ÷
2
100
)
                                             = 500000 + 25000000 m + 500000 m × 1 + 500000 m m ÷
2
100
                                             = 500000 + 25000000 m + 500000 m + 25000000 m m
                                             = 500000 + 25500000 m + 25000000 m m
    The equation is transformed into :
     500000 + 25500000 m + 25000000 m m = 660000

    
        m=20
    
    There are 1 solution(s).
