Answer 1

$frac{6}{7} - frac{2}{3} = frac{17-14} {21} = frac{4}{21}$
$frac{11}{12} - frac{5}{6} = frac{11-10}{12} = frac{1}{12}$
$frac{11}{16} - frac{5}{12} = frac{33-20}{48} = frac{13}{48}$
$frac{8}{21} - frac{4}{35} = frac{40-12}{105} = frac{28}{105} = frac{4}{15}$
$frac{7}{12} - frac{3}{8} = frac{14-9}{24} = frac{5}{24}$
$frac{9}{14} - frac{19}{35} = frac{45-18}{70} = frac{27}{70}$
