Answer 1

Explicación paso a paso:

$\frac{6}{5} + 2 \frac{1}{3} + 3 \frac{6}{5} + 4 \frac{5}{7} = \\ \\ \frac{6}{5} + \frac{3 \times 2 + 1}{3} + \frac{5 \times 3 + 6}{5} + \frac{7 \times 4 + 5}{7} = \\ \\ \frac{6}{5} + \frac{7}{3} + \frac{21}{5} + \frac{33}{7} = \\ \\ \frac{126 + 245 + 441 + 495}{105} = \frac{1.307}{105} \\ \\ \\ - 8 \frac{1}{2} + 6 \frac{1}{3} + \frac{75}{100} - \frac{6}{10} + \frac{3}{10} = \\ \\ \frac{2 \times ( - 8) + 1}{2} + \frac{3 \times 6 + 1}{3} + \frac{3}{4} - \frac{3}{10} = \\ \\ - \frac{15}{2} + \frac{19}{3} + \frac{3}{4} - \frac{3}{10} = \\ \\ \frac{ - 450 + 380 + 45 - 18}{60} = - \frac{43}{60}$
