Answer 1

$5\frac{2}{3} - 4\frac{1}{3} = \frac{17}{3} - \frac{13}{3} = \frac{4}{3} = 1\frac{1}{3}$
$12\frac{1}{3} - 9\frac{1}{4} = \frac{37}{3} - \frac{37}{4} = \frac{148-111}{12} = \frac{37}{12} = 3\frac{1}{12}$
$5 \frac{2}{3} - \frac{1}{6} = \frac{17}{3} - \frac{1}{6} = \frac{34-1}{6} = \frac{33}{6} = \frac{11}{2} =5 \frac{1}{2}$
$10 \frac{8}{9} - \frac{2}{3} = \frac{98}{9} - \frac{2}{3} = \frac{98-6}{9} = \frac{92}{9} = 10\frac{2}{9}$
$6\frac{3}{4} - 2\frac{1}{2} = \frac{27}{4} - \frac{5}{2} = \frac{27-10}{4} = \frac{17}{4} =4 \frac{1}{4}$
$4\frac{3}{5} - 1\frac{1}{10} = \frac{23}{5} - \frac{11}{10} = \frac{46-11}{10} = \frac{35}{10} = 3\frac{5}{10}$
