[tex]3\frac{7}{10}\times\frac{6}{1}=\frac{37}{10}\times\frac{6}{1}=\frac{37\times6}{10\times1}=\frac{222}{10}=22.2[/tex]
other
[tex]\frac{27}{10}\times\frac{15}{3}=\frac{27\times15}{10\times3}=\frac{405}{30}=13.5[/tex]
other
[tex]4\times2\frac{7}{10}=4\times\frac{27}{10}=\frac{4\times27}{10}=\frac{108}{10}=10.8[/tex]
therefore, the order from least to greatest is:
[tex]\begin{gathered} 4\times2\frac{7}{10}\text{ } \\ \frac{27}{10}\times\frac{15}{3}\text{ } \\ 3\frac{7}{10}\times\frac{6}{1} \end{gathered}[/tex]
