$$2\frac{1}{2} = \frac{2*2+1}{2} = \frac{5}{2}$$;
$$4\frac{3}{7} = \frac{4*7+3}{7} = \frac{31}{7}$$;
$$5\frac{6}{13} = \frac{5*13+6}{13} = \frac{71}{13}$$;
$$1\frac{2}{10} = \frac{1*10+2}{10} = \frac{12}{10} = \frac{6}{5}$$;
$$10\frac{3}{5} = \frac{10*5+3}{5} = \frac{53}{5}$$.
Ответ: $$2\frac{1}{2} = \frac{5}{2}$$; $$4\frac{3}{7} = \frac{31}{7}$$; $$5\frac{6}{13} = \frac{71}{13}$$; $$1\frac{2}{10} = \frac{6}{5}$$; $$10\frac{3}{5} = \frac{53}{5}$$.
