Logarithms as used in calculations don't "have" fractions since they are generally written as decimal numbers. But if you must have fractions, convert the fraction to a decimal and then look up the log of that. Or look up the log of the top and subtract the log of the bottom to get the log of what it stands for. Dividing a log by 2 gives the log of the square root of the number belonging to the original log. If you want the log of 13 1/2 (thirteen and a half) this is the log of 13.5 so you look up the log of 1.35 and add on 1
