Answer 1

Ответ:

$1)\ \ \ \displaystyle 6\frac{2}{*}-4\frac{*}{5}=*\frac{*-3}{15}\\\\\\2+\Big(\frac{2}{*}-\frac{*}{5}\Big)=2+\Big(\frac{2}{3}-\frac{1}{5}\Big)=2+\frac{10-3}{15}=2\frac{10-3}{15}=2\frac{7}{15}\\\\\\6\frac{2}{3}-4\frac{1}{5}=2\frac{10-3}{15}$

$2)\ \ \displaystyle *-1\frac{5}{6}=8\frac{*}{*}-1\frac{5}{6}=*\frac{1}{*}\\\\\\{}*-1\frac{5}{6}=8\frac{6}{6}-1\frac{5}{6}=7\frac{1}{6}\\\\\\9-1\frac{5}{6}=7\frac{1}{6}$
