(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

There are two equations and 3 variables and I'm asked to solve for the numerical value of a third expression:

We are told that

P/R=3/5

P/T=9/10

The question asks for the value of (R+T)/R

2. Relevant equations

The correct answer is 5/3 but I have no idea how to get there. This is from a GRE practice test.

3. The attempt at a solution

I tried addin' em together. Also solving for "P" to get rid of it doesn't work right away.
