Answer 1

$\large\boxed{\begin{array}{l}\sf a)~\rm\dfrac{8}{4}=\dfrac{4}{x}\\\\\rm2=\dfrac{4}{x}\\\\\rm 2x=4\\\\\rm x=\dfrac{4}{2}\\\\\rm x=2\\\\\rm\dfrac{8}{4}=\dfrac{6}{y}\\\\\rm 2=\dfrac{6}{y}\\\\\rm 2y=6\\\\\rm y=\dfrac{6}{2}\\\\\rm y=3\end{array}}$

$\large\boxed{\begin{array}{l}\sf b)~\rm\dfrac{x}{4}=\dfrac{6}{3}\\\\\rm\dfrac{x}{4}=2\\\\\rm x=2\cdot4\\\rm x=8\\\rm\dfrac{y}{5}=\dfrac{6}{3}\\\\\rm\dfrac{y}{5}=2\\\\\rm y=5\cdot2\\\rm y=10\end{array}}$
