Hello i apoligise if this is in the wrong forum but, i was wondering could anyone be kind enough to explain how i would work out the following problem on paper

if i had 70 calls and 24 of those were loan applications, what % of my calls were loan applications?

I think using a calculator i would 24/70=0.34 x100 =34% for my answer.

However how would i do this without a calculator? im not sure how i would work this division out on paper.

thanks in advance
