Ответ:
Преобразуем числа в дроби:
\(19,6=\frac{98}{5}\), \(2\frac{1}{2}=\frac{5}{2}\), \(2,0625=\frac{33}{16}\), \(1\frac{5}{12}=\frac{17}{12}\).
\(\frac{98}{5}\cdot\frac{5}{2}=49\).
\(\frac{33}{16}-\frac{17}{12}=\frac{99}{48}-\frac{68}{48}=\frac{31}{48}\).
\(\frac{31}{48}:\frac{1}{8}=\frac{31}{48}\cdot8=\frac{31}{6}\).
\(49-\frac{31}{6}=\frac{294}{6}-\frac{31}{6}=\frac{263}{6}=43\frac{5}{6}\).
Ответ: \(43\frac{5}{6}\).
