  1. Giải đáp:
    a) 480 : x = 24 : 4
    480 : x = 6
            x = 480 : 6
            x = 80
    b) 729 : x = 17 – 8
    729 : x = 9
            x = 729 : 9
            x = 81

  2. $\text{a) 480 : x = 24 : 4}$
    $\text{480 : x = 6}$
    $\text{x = 480 : 6}$
    $\text{x = 80}$
    $\text{b) 729 : x = 17 – 8}$
    $\text{729 : x = 9}$
    $\text{x = 729 : 9}$
    $\text{x = 81}$
