  1. ~ Bạn tham khảo ~
    x xx 1/2 = 1/3
    x = 1/3 : 1/2
    x = 1/3 xx 2/1
    x=2/3
    ________________
    x : 4/5 = 5/1
    x = 5 xx 4/5
    x = 4
    _____________________
    2/9 : x = 2/3
    x = 2/9 : 2/3
    x = 2/9 . 3/2
    x = 3/9
    x=1/3

    $a)$ $x$ $×$  $\frac{1}{2}$ = $\frac{1}{3}$ 
    $x$ $=$ $\frac{1}{3}$ $:$ $\frac{1}{2}$
    $x$ $=$ $\frac{2}{3}.$ 
    $b)$ $x$ $:$ $\frac{4}{5}$ $=$ $\frac{5}{1}$ 
    $x$ $=$ $\frac{5}{1}$ $×$ $\frac{4}{5}$ 
    $x$ $=$ $\frac{20}{5}.$ 
    $c)$ $\frac{2}{9}$ $:$ $x$ $=$ $\frac{2}{3}$ 
    $x$ $=$ $\frac{2}{9}$ $:$ $\frac{2}{3}$ 
    $x$ $=$ $\frac{6}{18}= $ $\frac{1}{3}.$
