Answer 1

1st Picture:
$3)- \frac{6}{7} +\frac {10}{11} \\\\LCD:77 \\\\\frac{6}{7}* \frac{11}{11} + \frac{10}{11}*\frac{7}{7}= \frac{66}{77} + \frac{70}{77} = \frac{136}{77} = 1\frac{59}{77} \\ \\ 4) 3\frac{6}{7}* 2 \frac{1}{10}= \frac{27}{7} * \frac{21}{10} = \frac{567}{70} =\frac{81}{10} = 8\frac{1}{10} \\\\5)2\frac{1}{2}+3\frac{1}{3} \\\\LCD: 6 \\\\ 2\frac{3}{6} + 3\frac{2}{6} =5\frac{5}{6} \\\\6)5\frac{1}{8}*-6\frac{6}{11}=\frac{41}{8}* \frac{72}{11}=\frac{2952}{88}=\frac{369}{11}=33\frac{6}{11}$

2nd Picture:
