21. $\frac{3}{4}\left [ \overline{2\frac{1}{2}-\frac{3}{4}}\times \frac{4}{7}-\overline{\frac{1}{4}+\frac{1}{8}} \right ]-\left \{ \frac{3}{4}-\frac{1}{2}-\overline{\frac{1}{4}+\frac{1}{4}} \right \}\times \frac{1}{8}$

22. $\left ( 6\frac{1}{4}-3\frac{7}{8} \right )$ এর $\left ( \frac{2}{3}-\frac{5}{3} \right )$

$\left ( \frac{2}{3}-\frac{5}{3} \right )\div \left \{ 5-\left ( 2\frac{1}{2}-1\frac{1}{2} \right ) \right \}$

23. $\left ( 2\frac{2}{3}+5\frac{7}{9} \right )\div \left ( 1\frac{1}{2}-\frac{4}{9} \right )\div (\frac{2}{25}$ এর $\frac{7}{42}$

এর $\frac{21}{56})$

24. $2-[ \frac{1}{4}\div \frac{13}{19}$ এর $\left \{ 2\frac{3}{20}-\left ( 4\frac{1}{4}-2\frac{1}{2} \right ) \right \}]$

25. $\left [ 1\frac{1}{3}-\left \{ \frac{7}{8}-\left ( \frac{1}{2}-\frac{1}{4}\div \overline{\frac{1}{3}+\frac{1}{2}} \right ) \right \} \right ]\times \frac{3}{4}$

26. $\left ( 1\frac{1}{4}+\frac{4}{5} \right )$ এর $\left ( 1\frac{1}{4}-\frac{4}{5} \right )$ $\div \left ( \frac{5}{6}+1\frac{1}{5} \right )$ এর $\left ( 1\frac{1}{5}-\frac{5}{6} \right )$

27. $8-8\left ( 2\frac{1}{5}-1\frac{2}{7} \right )\div \left [ 2-1\div \left ( 6-\frac{1}{6} \right ) \right ]$

28. $\left ( \frac{2}{7}-\frac{2}{49} \right )$ এর $\left ( \frac{1}{3}-\frac{1}{9} \right )\div \left ( \frac{2}{3}-\frac{2}{9} \right )$ এর $\left ( \frac{1}{7}-\frac{1}{49} \right )$

29. প্রমান করো যে
$\left [ \left ( 7\frac{5}{7} -2\frac{4}{21}\right )\div 4\frac{5}{6} +\frac{6}{7}\right ]-1=\left ( 1\frac{1}{4}+\frac{5}{6} \right )\div \left ( \frac{11}{12}+1\frac{1}{6} \right )$
