Accepted Answer

а) $\frac{1}{5} + \frac{53}{50} = \frac{1 × 10}{5 × 10} + \frac{53}{50} = \frac{10}{50} + \frac{53}{50} = \frac{10+53}{50} = \frac{63}{50}$
б) $\frac{1}{5} + \frac{19}{20} = \frac{1 × 4}{5 × 4} + \frac{19}{20} = \frac{4}{20} + \frac{19}{20} = \frac{4+19}{20} = \frac{23}{20}$
в) $\frac{1}{2} + \frac{33}{50} = \frac{1 × 25}{2 × 25} + \frac{33}{50} = \frac{25}{50} + \frac{33}{50} = \frac{25+33}{50} = \frac{58}{50} = \frac{29}{25}$
г) $\frac{1}{5} - \frac{41}{50} = \frac{1 × 10}{5 × 10} - \frac{41}{50} = \frac{10}{50} - \frac{41}{50} = \frac{10-41}{50} = -\frac{31}{50}$

Ответ: а) $\frac{63}{50}$, б) $\frac{23}{20}$, в) $\frac{29}{25}$, г) -$\frac{31}{50}$.
