[tex](6 \frac{3}{4} -5 \frac{3}{8}) \div (15 \frac{4}{9} -3 \frac{6}{7} ) \\ =(6 \frac{6}{8}-5 \frac{3}{8})\div(15 \frac{28}{63}-3 \frac{54}{63}) \\ =1 \frac{3}{8}\div(14 \frac{91}{63}-3 \frac{54}{63}) \\ = \frac{11}{8}\div11 \frac{37}{63} \\ = \frac{11}{8}\div \frac{730}{63} \\ = \frac{11}{8}\times \frac{63}{730} \\ = \frac{693}{5840} [/tex]
