Answer to Question #299251 in Algebra for Philly

Question

In a triangle side x is 3/5 if side z. If y is 3/4 of side x,. What is the ratio of y to z?

Answer 1

Given, in a triangle side x is 3/5 of side z and y is 3/4 of side x.

This can be written in the equation as, $x= \dfrac{3}{5}z~\text{and } y = \dfrac{3}{4}x$.

That is, $y = \dfrac{3}{4}\cdot\dfrac{3}{5}z=\dfrac{9}{20}z$.

Therefore, $y:z=9:20.$
