remember
[tex](\frac{a}{b}) \space\ times \space\ (\frac{c}{d})=[/tex]
[tex]\frac{a \space\ times \space\ c}{b \space\ times \space\ d}=[/tex]
[tex]\frac{ac}{bd}[/tex]

remember that [tex]a=\frac{a}{1}[/tex]

therefor

[tex]2 \space\ times \space\ \frac{3}{7}=[/tex]
[tex]\frac{2}{1}\space\ times \space\ \frac{3}{7}=[/tex]
[tex]\frac{2*3}{1*7}=[/tex]
[tex]\frac{6}{7}[/tex]
