Решите уравнение:
а) $\frac{12}{17} * t = \frac{4}{7} * \frac{24}{51}$;
б) $\frac{18}{25} * \frac{6}{35} = t * \frac{27}{175}$;
в) $t * \frac{8}{13} = \frac{28}{91} * \frac{6}{7}$.
$\frac{12}{17} * t = \frac{4}{7} * \frac{24}{51}$
$t = \frac{4}{7} * \frac{24}{51} : \frac{12}{17}$
$t = \frac{4}{7} * \frac{24}{51} * \frac{17}{12}$
$t = \frac{4}{7} * \frac{2}{3} * \frac{1}{1}$
$t = \frac{8}{21}$
$\frac{18}{25} * \frac{6}{35} = t * \frac{27}{175}$
$t = \frac{18}{25} * \frac{6}{35} : \frac{27}{175}$
$t = \frac{18}{25} * \frac{6}{35} * \frac{175}{27}$
$t = \frac{2}{5} * \frac{2}{1} * \frac{1}{1}$
$t = \frac{4}{5}$
$t * \frac{8}{13} = \frac{28}{91} * \frac{6}{7}$
$t = \frac{28}{91} * \frac{6}{7} : \frac{8}{13}$
$t = \frac{28}{91} * \frac{6}{7} * \frac{13}{8}$
$t = \frac{1}{7} * \frac{3}{1} * \frac{1}{1}$
$t = \frac{3}{7}$
