Answer 1

$6 \frac{3}{4} -\frac{11}{4} -1 \frac{2}{5} = \\ \\ \frac{27}{4} - \frac{11}{4}- \frac{7}{5} = \\ \\ \frac{27-11}{4} - \frac{7}{5}= \\ \\ \frac{16}{4}- \frac{7}{5} = \\ \\ 4- \frac{7}{5}= \\ \\ \frac{13}{5} \\ \\ \\ \frac{16}{7} +2 \frac{5}{14} -4 \frac{1}{2} = \\ \\ \frac{16}{7}+ \frac{33}{14} - \frac{7}{2} = \\ \\ \frac{32+33-49}{14} = \\ \\ \frac{65-49}{14} = \\ \\ \frac{16}{14} = \\ \\ \frac{8}{7}$
