    Đề bài : $\dfrac{x × 100}{0,01}$ = 0,55 + 15,88
    _____________________________________________ 
    \text{(x × 100 – 0,7357) : 0,01 = 16,43}
    \text{x × 100 : 0,01 – 0,7357 : 0,01 = 16,43}
    \text{x × 10000 – 73,57 = 16,43}
    \text{x × 10000 = 16,43 + 73,57}
    \text{x × 10000 = 90}
    \text{x = 90 : 10000}
    \text{x = 0,009}

    ( X × 100 – 0,7357 ) ÷ 0,01 = 0,55 + 15,88
    ( X × 100 – 0,7357 ) ÷ 0,01 = 16, 43
    ( X × 100 – 0,7357 ) = 16, 43 × 0,01
    X × 100 – 0,7357 = 0,1643
    X × 100 = 0,1643 + 0,7357
    X ×100 = 0,918
    X = 0,918 ÷ 100
    X = …………
