e).
$\frac{19}{140} - \frac{11}{210} = \\ \\ \\ 1 \times \frac{1}{12} - \frac{3}{4} - \frac{5}{18} = \\ \\ \\ \frac{3}{14} - ( \frac{5}{28} - \frac{11}{24} )$
f).
$5 \times \frac{3}{8} - 3 \times \frac{5}{16} - 1 \times \frac{7}{12} \\ \\ \\ \frac{5}{48} - \frac{1}{36} - \frac{1}{72} - \frac{1}{96} = \\ \\ \\ 4 \times \frac{1}{14} - 2 \times \frac{5}{21} - 1 \times \frac{3}{28} =$
