$1\frac{2}{3}+4\frac{5}{3}=\frac{1\times 3+2}{3}+\frac{4\times 3+5}{3}=\frac{…+…}{…}=\frac{…}{…}$

$1\frac{2}{3}+4\frac{5}{3}=\frac{1\times 3+2}{3}+\frac{4\times 3+5}{3}=\frac{5+17}{3}=\frac{22}{3}$

$6\frac{2}{7}-4\frac{5}{7}=\frac{6\times …+2}{7}-\frac{4\times …+5}{7}=\frac{…-…}{…}=\frac{…}{…}$

$6\frac{2}{7}-4\frac{5}{7}=\frac{6\times 7+2}{7}-\frac{4\times 7+5}{7}=\frac{44-33}{7}=\frac{11}{7}$

$1\frac{5}{3}+4\frac{2}{7}=\frac{8}{3}+\frac{30}{7}=\frac{…}{3\times 7}+\frac{…}{7\times 3}=\frac{…}{…}$

$1\frac{5}{3}+4\frac{2}{7}=\frac{8}{3}+\frac{30}{7}=\frac{8\times 7}{3\times 7}+\frac{30\times 3}{7\times 3}=\frac{56+90}{21}=\frac{146}{7}$

$3\frac{5}{4}-1\frac{2}{3}=\frac{…}{…}-\frac{…}{…}=\frac{…}{…}-\frac{…}{…}=\frac{…}{…}

$3\frac{5}{4}-1\frac{2}{3}=\frac{17}{4}-\frac{5}{3}=\frac{51}{12}-\frac{20}{12}=\frac{31}{12}

$3\frac{5}{4}\times 1\frac{2}{3}=\frac{…}{…}\times\frac{…}{…}=\frac{…}{…}

$3\frac{5}{4}\times 1\frac{2}{3}=\frac{17}{4}\times\frac{5}{3}=\frac{85}{12}

$3\frac{5}{4}\times\frac{2}{3}=\frac{…}{…}\times\frac{…}{…}=\frac{…}{…}

$3\frac{5}{4}\times\frac{2}{3}=\frac{17}{4}\times\frac{2}{3}=\frac{34}{12}

$3\frac{5}{4}\times 6=\frac{…}{…}\times\frac{…}{…}=\frac{…}{…}

$3\frac{5}{4}\times 6=\frac{17}{4}\times\frac{6}{1}=\frac{102}{4}

$3\frac{1}{2}:1\frac{2}{3}=\frac{…}{…}:\frac{…}{…}=\frac{…}{…}\times\frac{…}{…}=\frac{…}{…}

$3\frac{1}{2}:1\frac{2}{3}=\frac{7}{2}:\frac{5}{3}=\frac{7}{2}\times\frac{3}{5}=\frac{21}{10}

$\frac{1}{2}:4\frac{2}{3}=\frac{…}{…}:\frac{…}{…}=\frac{…}{…}\times\frac{…}{…}=\frac{…}{…}

$\frac{1}{2}:4\frac{2}{3}=\frac{1}{2}:\frac{14}{3}=\frac{1}{2}\times\frac{3}{14}=\frac{3}{28}

$5:4\frac{2}{3}=\frac{…}{…}:\frac{…}{…}=\frac{…}{…}\times\frac{…}{…}=\frac{…}{…}

$5:4\frac{2}{3}=\frac{5}{1}:\frac{14}{3}=\frac{5}{1}\times\frac{3}{14}=\frac{15}{14}
