Question

In the figure below, the ratio of AB to DE or the ratio of AC to DF is the same as the ratio of 5 to 4. Find the ratio of x to y.

Answer 1

solve
\[\frac{x+16}{16}=\frac{y+7}{20}\] would probably be easiest

Answer 2

well no, actually easiest would be
\[\frac{x+16}{4}=\frac{y+7}{5}\]

Answer 3

same thing though just smaller numbers.
