    get common denominators, and bring the right sid eof the division below. \[\huge \frac{\frac{1}{x}+\frac{2}{y}}{\frac{2}{x}+\frac{1}{y}}=\frac{\frac{y+2x}{xy}}{\frac{2y+x}{xy}}\] now anything common between the numerators cancal, and anythign common between the denominators cancel

    Alternately, and maybe more appealing is the invert and multiply \[\huge =\frac{y+2x}{xy} \times \frac{xy}{2y+x}\]
