\[ \frac{5}{22} + \frac{8}{11} = \frac{5}{22} + \frac{8 \times 2}{11 \times 2} = \frac{5}{22} + \frac{16}{22} = \frac{5 + 16}{22} = \frac{21}{22} \]
\[ 6 \frac{1}{2} + \frac{21}{22} = 6 + \frac{1}{2} + \frac{21}{22} \]
\[ 6 + \frac{1 \times 11}{2 \times 11} + \frac{21}{22} = 6 + \frac{11}{22} + \frac{21}{22} = 6 + \frac{11 + 21}{22} = 6 + \frac{32}{22} \]
\[ 6 + \frac{32}{22} = 6 + \frac{32 \div 2}{22 \div 2} = 6 + \frac{16}{11} \]
\[ 6 + \frac{16}{11} = 6 + 1 \frac{5}{11} = 7 \frac{5}{11} \]
