Answer 1

1
$2 \times \frac{1}{3} - 1 \times \frac{1}{2} = \frac{7}{3} - \frac{3}{2} = \frac{14}{6} - \frac{9}{6} = \frac{5}{6}$
2.
$4 \times \frac{1}{5} - 2 \times \frac{3}{10} = \frac{21}{5} - \frac{23}{10} = \frac{42}{10} - \frac{23}{10} = \frac{19}{10}$
3.
$7 \times \frac{1}{9} - 4 \times \frac{1}{3} = \frac{64}{9} - \frac{13}{3} = \frac{64}{9} - \frac{39}{9} = \frac{25}{9}$
