Question

(2 целых 4/5 - 3 целых 7/15)умножить на 1/8

Answer 1

$( 2 \frac{4}{5} -3 \frac{7}{15} )* \frac{1}{8} = ( \frac{14}{5} - \frac{52}{12} ) * \frac{1}{8} = \frac{45-52}{15} * \frac{1}{8} = (-\frac{10}{15} ) * \frac{1}{8} =$
$- \frac{2}{3} * \frac{1}{8} = - \frac{1}{3} * \frac{1}{4} = - \frac{1}{12}$
