remember that [tex]\frac{\frac{a}{b}}{\frac{c}{d}}=(\frac{a}{b})(\frac{d}{c})=\frac{ad}{bc}[/tex]
try and simpliy each first
4y/14=(2/2)(2y/7)=2y/7
so 2x/7 divided by 2y/7
[tex]\frac{\frac{2x}{7}}{\frac{2y}{7}}=(\frac{2x}{7})(\frac{7}{2y})=\frac{(2x)(7)}{(2y)(7)}[/tex] = [tex]\frac{14x}{14y}=\frac{x}{y}[/tex]
