A fraction should always be simplified (even tho I encoutered problems earlier where a non-simplified fractions was OK) for one exception.. Probability. The fraction you obtain in probaility has a meaning (favourable outcomes/total number of outcomes). That's why it should be ok not to simplify fractions when doing probability. Thank you, and what a great site you have!
