Решите уравнение.
1) $\frac{4}{5}x = \frac{8}{15}$
$x = \frac{8}{15} : \frac{4}{5}$
x =
x =
2) $7x = \frac{3}{8}$
3) $\frac{3}{11}x = 9$
4) $x : 1\frac{13}{14} = 1\frac{17}{18}$
5) $2\frac{5}{8} : x = 1\frac{19}{20}$
6) $1\frac{8}{9}x = 6,8$
$\frac{4}{5}x = \frac{8}{15}$
$x = \frac{8}{15} : \frac{4}{5}$
$x = \frac{8}{15} * \frac{5}{4}$
$x = \frac{2}{3} * \frac{1}{1}$
$x = \frac{2}{3}$
Ответ: $\frac{2}{3}$
$7x = \frac{3}{8}$
$x = \frac{3}{8} : 7$
$x = \frac{3}{8} * \frac{1}{7}$
$x = \frac{3}{56}$
Ответ: $\frac{3}{56}$
$\frac{3}{11}x = 9$
$x = 9 : \frac{3}{11}$
$x = 9 * \frac{11}{3}$
$x = 3 * \frac{11}{1}$
x = 33
Ответ: 33
$x : 1\frac{13}{14} = 1\frac{17}{18}$
$x = 1\frac{17}{18} * 1\frac{13}{14}$
$x = \frac{35}{18} * \frac{27}{14}$
$x = \frac{5}{2} * \frac{3}{2}$
$x = \frac{15}{4}$
$x = 3\frac{3}{4}$
Ответ: $3\frac{3}{4}$
$2\frac{5}{8} : x = 1\frac{19}{20}$
$x = 2\frac{5}{8} : 1\frac{19}{20}$
$x = \frac{21}{8} : \frac{39}{20}$
$x = \frac{21}{8} * \frac{20}{39}$
$x = \frac{7}{2} * \frac{5}{13}$
$x = \frac{35}{26}$
$x = 1\frac{9}{26}$
Ответ: $1\frac{9}{26}$
$1\frac{8}{9}x = 6,8$
$1\frac{8}{9}x = 6\frac{8}{10}$
$1\frac{8}{9}x = 6\frac{4}{5}$
$x = 6\frac{4}{5} : 1\frac{8}{9}$
$x = \frac{34}{5} : \frac{17}{9}$
$x = \frac{34}{5} * \frac{9}{17}$
$x = \frac{2}{5} * \frac{9}{1}$
$x = \frac{18}{5}$
$x = 3\frac{3}{5}$
Ответ: $3\frac{3}{5}$
