[tex]20 \frac{4}{5} - \frac{7}{9} \\ = \frac{104}{5} - \frac{7}{9} \\ = \frac{936}{45} - \frac{35}{45} \\ = \frac{901}{45} \\ = 20 \frac{1}{45} [/tex]
[tex]16 \frac{5}{7} - 2 \frac{1}{4} \\ = \frac{117}{7} - \frac{9}{4} \\ = \frac{468}{28} - \frac{63}{28} \\ = \frac{405}{28} \\ = 14 \frac{13}{28} [/tex]
