Answer 1

1) $3\frac{6}{11} + 9\frac{3}{11} = 12 \frac{9}{11}$

2) $(9\frac{5}{18} + 6\frac{1}{12} ) - 11\frac{4}{9} = ((9+6) +(\frac{5}{18}+\frac{1}{12} )) - \frac{103}{9}$$(15+\frac{13}{36} ) - \frac{103}{9} = 15\frac{13}{36} - \frac{103}{9} =\frac{553}{36} - \frac{103}{9} =\frac{47}{12} = 3\frac{11}{12}$

3) $9 - 5\frac{3}{13} = 9 - \frac{68}{13} = \frac{117}{13} - \frac{68}{13} = \frac{49}{13} = 3\frac{10}{13}$
