Find some values that satisfy the given equations.

Start with \(s=3t\) and \(2t=p\)
If \(t=1\), then \(s=3\) and \(p=2\)

Now we can deal with \(r=6s\)
Since \(s=3\), we know that \(r=18\)

Since the values \(t=1\), \(s=3\), \(p=2\) and \(r=18\) satisfy all of the given equations, we can now answer the question...

\(\frac{p}{r}=\frac{2}{18}=\frac{1}{9}\)

Answer: 1/9

Thanks Brent

very simple
2t/6x3t

on solving we are left with the answer
1/9

please give a kudos;)
