Question

3 1/5 divided by 1 1/3.

Answer 1

\[3\frac{1}{5}=\frac{3*5+1}{5}=\frac{16}{5}\]
\[1\frac{1}{3}=\frac{1*3+1}{3}=\frac{4}{3}\]
\[\frac{\frac{16}{5}}{\frac{4}{3}}\]
\[\frac{16}{5}*\frac{3}{4}\]
\[\frac{4}{5}*\frac{3}{1}\]
\[\frac{12}{5}\]

Answer 2

\[\frac{3+\frac{1}{5}}{1+\frac{1}{13}}\text{=}\frac{\frac{16}{5}}{\frac{14}{13}}\text{=}\frac{16}{5}\left(\frac{13}{14}\right)\text{=}\frac{104}{35}\]
