You're posting a lot of very similar questions.  If you really want to learn this stuff, I suggest that you spend a lot of time really understanding the answer to one problem before moving onto the next. I know it seems like all of these are completely different problems, but they're not; they're all done the exact same way.

So, what does the denominator have to be?  The denominator of one is 5, the denominator of the other is 3...what number is a multiple of 5 and 3?
