Solving for Gas Law variables question

Hey everyone!

When solving for gas law variables, I know there are two main equations you can use:

pV=nRT or p2v2/p1v1= n2t2/n1t1

Which one is EASIER to use with respect to estimating (since no calculator)? It's kind of hard to divide by 0.08 sometimes, or use that R in general, so I've used method 2, but what are your suggestions?

Thanks in advance!

I prefer using PV = nRT.......R can always be estimated to be 0.1.
