Answer 1

Ответ:

$\frac{3905}{8}$

Пошаговое объяснение:

$(\frac{21}{2} - \frac{13}{8} ) * (\frac{31}{2} - \frac{3}{6} )*\frac{11}{3}$

$(\frac{21}{2} * \frac{4}{4} - \frac{13}{8} ) * (\frac{31}{2} -\frac{3}{6} ) * \frac{11}{3}$

$(\frac{21*4}{8} - \frac{13}{8} ) * (\frac{31}{2} - \frac{3}{6} )*\frac{11}{3}$

$\frac{21*4-13}{8} * (\frac{31}{2} - \frac{3}{6} ) * \frac{11}{3}$

$\frac{71}{8} * (\frac{31}{2} - \frac{3}{6} )*\frac{11}{3}$

$\frac{71}{8} * (\frac{31}{2} - \frac{1}{2} )*\frac{11}{3}$

$\frac{71}{8} *\frac{31-1}{2} *\frac{11}{3}$

$\frac{71}{8} *\frac{30}{2} *\frac{11}{3}$

$\frac{71}{4} * \frac{15}{2} * \frac{11}{3}$

$\frac{71*15}{4*2} * \frac{11}{3}$

$\frac{1065}{8} * \frac{11}{3}$

$\frac{355}{8} * 11$

$\frac{355*11}{8}$

$\frac{3905}{8}$
