Решите пример 3/4*7/80-3/4*(7/8-2/3)

[latex] \frac{3}{4}* \frac{7}{80} - \frac{3}{4}* (\frac{7}{8} - \frac{2}{3})= \frac{21}{320} - \frac{3}{4} *( \frac{21}{24} - \frac{16}{24})=\frac{21}{320}- \frac{3}{4} * \frac{5}{24} = \frac{21}{320} - \frac{5}{32}= \frac{21}{320}- \frac{50}{320} = -\frac{29}{320} [/latex]
