Question

вычислите 2 1/3+4 1/10+( 2 7/15-5/12)* 5/6

Answer 1

$2 \frac{10}{30} +4 \frac{3}{30}+(2 \frac{28}{60} - \frac{25}{60} )* \frac{5}{6} =6 \frac{13}{30} +2 \frac{3}{60} * \frac{5}{6} = 6 \frac{13}{30} + \frac{123}{60} * \frac{5}{6}=$
$=6 \frac{13}{30} + 1\frac{17}{24} =6 \frac{52}{120} +1 \frac{85}{120} =7 \frac{137}{120} =8 \frac{17}{120}$
