6. The fraction can be written as;

$\frac{x^2}{2y} /\frac{y^2}{4} \\\\\frac{x^2}{2y} *\frac{4}{y^2} \\\\$

Divide 4 by 2

= $\frac{2x^2}{y^3}$

The fraction can be written as;

$\frac{b^2}{6} /\frac{b}{a}$

introduce product sign as

$\frac{b^2}{6} *\frac{a}{b} \\\\=b*a/6\\=\frac{ab}{6}$

The fraction can be written as;

$\frac{x}{y} /\frac{yx}{2}$

Introduce product sign

$\frac{x}{y} *\frac{2}{yx} \\\\=\frac{2}{y^2}$

The fraction can be written as;

$\frac{x}{y^2} /\frac{x}{y} \\\\\\=\frac{x}{y^2} *\frac{y}{x} \\\\\\=\frac{1}{y}$

10.

The fraction is simplified to;

$\frac{x}{3y} /\frac{9}{x} \\\\\\\frac{x}{3y} *\frac{x}{9} =\frac{x^2}{27y}$
