Find the product :

$7\dfrac{1}{4}\times2\dfrac{3}{16}\times2\dfrac{2}{7}$

We have:

$\begin{array}{ll} \phantom{=} 7\dfrac{1}{4}\times2\dfrac{3}{16}\times2\dfrac{2}{7} \\ = \dfrac{29}{4} \times \dfrac{35}{16} \times \dfrac{16}{7} & \text{[Converting mixed fraction to improper fraction]} \\ = \dfrac{29}{4} \times \dfrac{35}{1} \times \dfrac{1}{7} & \text{[Simplifying 16 and 16 ⇒ Divide by 16 ]} \\ = \dfrac{29}{4} \times \dfrac{5}{1} \times \dfrac{1}{1} & \text{[Simplifying 35 and 7 ⇒ Divide by 7 ]} \\ = \dfrac{29 \times 5 \times 1}{4 \times 1 \times 1} \\ = \dfrac{145}{4} \\ = 36\dfrac{1}{4} & \text{[Converting improper to mixed fraction]} \end{array}$

∴ The answer is $36\dfrac{1}{4}$
