⇒916×1415⇒915×1416⇒35×78⇒2140.\Rightarrow \dfrac{9}{16} \times \dfrac{14}{15}\\[1em] \Rightarrow \dfrac{9}{15} \times \dfrac{14}{16} \\[1em] \Rightarrow \dfrac{3}{5} \times \dfrac{7}{8} \\[1em] \Rightarrow \dfrac{21}{40}.⇒169×1514⇒159×1614⇒53×87⇒4021.
Hence, 916×1415=2140\dfrac{9}{16} \times \dfrac{14}{15} = \dfrac{21}{40}169×1514=4021.
