$\frac{ 11}{30} - \frac{2}{5} \times \frac{1}{6} =$
​

Answer 1

$\frac{11}{30} -\frac{2}{5} *\frac{1}{6}$

1) $\frac{2}{5}*\frac{1}{6} =\frac{2*1}{5*6} =\frac{1*1}{5*3} =\frac{1}{15}$

2) $\frac{11}{30} -\frac{1}{15} =\frac{11}{30} -\frac{2}{30} =\frac{11-2}{30} =\frac{9}{30}$

Ответ: $\frac{9}{30}$.

Удачи!!!
