PaperPrincess-- yes, to round up---look at the first whole number and go up to the next one like it, so if it's even you go up to the next even number then you look at the fraction and go up to the next whole number, that's why 2 and 1/4 gets rounded up to 5. However in the olden days (also known as pre-fm times) you would keep the whole number the same, but round up the fraction and then put it beside the original whole number so 2and 1/4 would equal 21--- but only if it was a really good deal on a really really pretty fabric.....
