remember
[tex]\frac{\frac{a}{b}}{\frac{c}{d}}=(\frac{a}{b})(\frac{d}{c})=\frac{ad}{bc}[/tex]
or we can simplify a diferent way
[tex]\frac{\frac{4}{7}}{\frac{1}{3}}[/tex]
make denomenator an integer by multiplying the whole thing by [tex]\frac{\frac{3}{1}}{\frac{3}{1}}[/tex]
[tex]\frac{\frac{12}{7}}{\frac{3}{3}}[/tex]
[tex]\frac{\frac{12}{7}}{1}[/tex]
[tex]\frac{12}{7}[/tex]
the result is [tex]\frac{12}{7}[/tex]
