Answer 1

Answer:

$\frac{3}{5} + \frac{4}{3} + \frac{2}{3} \\ = \frac{9 + 20 + 10}{15} \\ = \frac{ \cancel{ 39} _{ \: \: 13} }{ \cancel{ 15} _{ \: \: 5}} \\ \boxed{ = \underline{ \underline{ \frac{13}{5} }}} \\ \\ \frac{2}{8} + \frac{3}{16} \\ = \frac{4 + 3}{16} \\ \boxed{ = \underline{ \underline{ \frac{7}{16} }}} \\ \\ \frac{3}{7} + \frac{4}{3} \\ = \frac{9 + 28}{21} \\ \boxed{ = \underline{ \underline{ \frac{37}{21} }}} \\ \\ \frac{8}{3} - \frac{2}{5} \\ = \frac{40 - 6}{15} \\ \boxed{ = \underline{ \underline{ \frac{34}{15} }}} \\ \\ \frac{6}{5} - \frac{3}{7} \\ = \frac{42 - 15}{35} \\ \boxed{ = \underline{ \underline{ \frac{27}{35} }}} \\ \\ \frac{9}{11} - \frac{3}{14} \\ = \frac{126 - 33}{154} \\ \boxed{ = \underline{ \underline{ \frac{93}{154} }}}$
