One question I am solving in the OG requires two fractions be added. That itself is not the answer or the purpose of the question, rather just one part of the question. And given there are only 2 minutes or so to solve the problem, this is going to be a nightmare if i dont find an easy way out.

So fraction being added is 1/15 + 1/18. Can anyone comment as to how this will be solved the quickest possible manner. 18*15 way of doing it is lengthy and would give a bigger multiple to struggle with.
