ПРОШУ МНЕ ОЧЕНЬ ОЧЕНЬ СРОЧНО!!!!!!!!!!!!!!!!!!

Решите задачу:

$\displaystyle a) \frac{1}{3} \cdot x = \frac {1}{6}$
$\displaystyle x= \frac{1}{6} : \frac{1}{3}$
$\displaystyle x= \frac{1}{2}$

$c) \displaystyle \frac{2}{3}m = 1$
$\displaystyle m=1: \frac{2}{3}$
$\displaystyle m= 1 \frac{1}{2}$

$\displaystyle b) \frac{2}{5}y=1 \frac{1}{5}$
$\displaystyle y= \frac{6}{5}: \frac{2}{5}$
$y=3$

$\displaystyle d) b \cdot 5= \frac{1}{5}$
$\displaystyle b= \frac{1}{5}:5$
$\displaystyle b= \frac{1}{10}$
