  1. $\text{a) x : 620 = 243}$
    <=> $\text{x = 243 . 620}$
    <=> $\text{x = 150 660}$
    $\text{Vậy x = 150 660}$
    $\text{b) x : 131 = 271}$
    <=> $\text{x = 271 . 131}$
    <=> $\text{x = 35 501}$
    $\text{Vậy x = 35 501}$
    $\text{c) x : 599 = 616}$
    <=> $\text{x = 616 . 599}$
    <=> $\text{x = 368 984}$
    $\text{Vậy x = 368 984}$
    $\text{d) x : 425 = 2012}$
    <=> $\text{x = 2012 . 425}$
    <=> $\text{855 100}$
    $\text{Vậy x = 855 100}$
