номер 913 помогите пжлст

Answer 1

а) $(-\frac{1}{2}) + (-5) = - \frac{1}{2} - 5 = -5\frac{1}{2}$
б) $(-7) + (-\frac{2}{3}) = -7 - \frac{2}{3} = -7\frac{2}{3}$
в) $(-\frac{1}{3})+(-\frac{1}{2})=-\frac{1}{3} - \frac{1}{2} = -\frac{2}{6} -\frac{3}{6} = -\frac{5}{6}$
г) $(-1\frac{2}{5})+(-\frac{1}{3}) = -1\frac{2}{5}-\frac{1}{3} = -1\frac{6}{15}-\frac{5}{15} = -1\frac{11}{15}$
