Answer 1

Explicación paso a paso:

$\frac{11}{5} - \frac{5}{3} = \frac{3 \times 11 - 5 \times 5}{5 \times 3} = \frac{33 - 25}{15} = \frac{8}{15}$

$7 + \frac{1}{2} - \frac{11}{5} = \frac{7 \times 10 + 1 \times 5 - 11 \times 2}{10} = \frac{70 + 5 - 22}{10} = \frac{53}{10}$

$\frac{16}{3} + \frac{8}{5} - \frac{1}{10} - \frac{2}{6} = \frac{10 \times 16 + 8 \times 6 - 1 \times 3 - 2 \times 5}{30} = \frac{160 + 48 - 3 - 10}{30} = \frac{195}{30}$

$\frac{12}{30} + \frac{16}{20} - \frac{1}{2} = \frac{12 \times 2 + 16 \times 3 - 1 \times 30}{60} = \frac{24 + 48 - 30}{60} = \frac{42}{60}$
