The value of $$(5\frac{1}{4}\div\frac{3}{7} of \frac{1}{2})\div(5\frac{1}{9}-7\frac{7}{8}\div9\frac{9}{20})\times \frac{11}{21}+(2 \div 2  of  \frac{1}{2})$$ is :

Given that $$(5\frac{1}{4}\div\frac{3}{7} of \frac{1}{2})\div(5\frac{1}{9}-7\frac{7}{8}\div9\frac{9}{20})\times \frac{11}{21}+(2 \div 2 of \frac{1}{2})$$

According to Bod mass Rule 

$$\Rightarrow (\frac{21}{4}\div\frac{3}{7} \times \frac{1}{2})\div(\frac{46}{9}-\frac{63}{8}\div \frac{189}{20})\times \frac{11}{21}+(2 \div 2 \times  \frac{1}{2})$$

$$\Rightarrow (\frac{21}{4} \times \frac{14}{3})\div(\frac{46}{9}-\frac{63}{8}\times \frac{20}{189})\times \frac{11}{21}+(2 \div 1)$$

$$\Rightarrow (\frac{21}{4} \times \frac{14}{3})\div(\frac{46}{9}-\frac{5}{6})\times \frac{11}{21}+2$$

$$\Rightarrow (\frac{49}{2})\div(\frac{92-15}{18})\times \frac{11}{21}+2$$

$$\Rightarrow (\frac{49}{2})\div(\frac{92-15}{18})\times \frac{11}{21}+2$$

$$\Rightarrow 3+2 $$

$$\Rightarrow 5 $$ Ans
