Решите уравнение:
1) $\frac{25}{27}x = \frac{5}{18}$;
2) $\frac{13}{17}x = 39$;
3) $4x = \frac{5}{7}$;
4) $x : 2\frac{2}{15} = 1\frac{9}{16}$;
5) $4\frac{4}{9} : x = \frac{5}{27}$;
6) $1\frac{4}{9}x = 5,2$.
$\frac{25}{27}x = \frac{5}{18}$
$x = \frac{5}{18} : \frac{25}{27}$
$x = \frac{5}{18} * \frac{27}{25}$
$x = \frac{1}{2} * \frac{3}{5}$
$x = \frac{3}{10}$
$\frac{13}{17}x = 39$
$x = 39 : \frac{13}{17}$
$x = 39 * \frac{17}{13}$
x = 3 * 17
x = 51
$4x = \frac{5}{7}$
$x = \frac{5}{7} : 4$
$x = \frac{5}{7} * \frac{1}{4}$
$x = \frac{5}{28}$
$x : 2\frac{2}{15} = 1\frac{9}{16}$
$x = \frac{25}{16} * \frac{32}{15}$
$x = \frac{5}{1} * \frac{2}{3}$
$x = \frac{10}{3} = 3\frac{1}{3}$
$4\frac{4}{9} : x = \frac{5}{27}$
$x = 4\frac{4}{9} : \frac{5}{27}$
$x = \frac{40}{9} * \frac{27}{5}$
$x = \frac{8}{1} * \frac{3}{1}$
x = 24
$1\frac{4}{9}x = 5,2$
$x = 5,2 : 1\frac{4}{9}$
$x = 5,2 * \frac{9}{13}$
x = 0,4 * 9
x = 3,6
