I am having problems finding the ratio of this can someone help me please.
Simply set up your equations and solve for the variables:
$\displaystyle \frac{AB}{DE} = \frac{5}{4}$
$\displaystyle \frac{x + 16}{16} = \frac{5}{4}$
$\displaystyle \frac{AC}{DF} = \frac{5}{4}$
$\displaystyle \frac{y + 7}{20} = \frac{5}{4}$
Once you solve for them, figure out what $\displaystyle \frac{x}{y}$ is.
