$a) \frac{2}{7} × x = \frac{2}{3}$
$⇒ x = \frac{2}{3} ÷ \frac{2}{7}$
$⇒ x = \frac{7}{3}$
$Vậy$ $x = \frac{7}{3}$
$b) \frac{3}{5} ÷ x = \frac{1}{3}$
$⇒ x = \frac{3}{5} ÷ \frac{1}{3}$
$⇒ x = \frac{9}{5}$
$Vậy$ $x = \frac{9}{5}$
$c) x ÷ \frac{7}{11} = 22$
$⇒ x = 22 × \frac{7}{11}$
$⇒ x = 14$
$Vậy$ $x = 14$
$d) x - \frac{3}{2} = \frac{11}{4}$
$⇒ x = \frac{11}{4} + \frac{3}{2}$
$⇒ x = \frac{17}{4}$
$Vậy$ $x = \frac{17}{4}$
$e) x + \frac{5}{4} = \frac{3}{2}$
$⇒ x = \frac{3}{2} - \frac{5}{4}$
$⇒ x = \frac{1}{4}$
$Vậy$ $x = \frac{1}{4}$
