The value of $$\frac{5}{{1\frac{7}{8}{\text{of 1}}\frac{1}{3}}} \times \frac{{2\frac{1}{{10}}}}{{3\frac{1}{2}}}{\text{ of 1}}\frac{1}{4} = ?$$

$$\eqalign{ & {\text{According to the question}} \cr & \frac{5}{{1\frac{7}{8}{\text{of 1}}\frac{1}{3}}} \times \frac{{2\frac{1}{{10}}}}{{3\frac{1}{2}}}{\text{ of 1}}\frac{1}{4} \cr & \Rightarrow \frac{5}{{\frac{{15}}{8} \times {\text{ }}\frac{4}{3}}} \times {\text{ }}\frac{{21}}{{10}} \times \frac{2}{7} \times \frac{5}{4} \cr & \Rightarrow 2 \times \frac{3}{4} \cr & \Rightarrow \frac{3}{2} \cr & \Rightarrow 1\frac{1}{2} \cr} $$
