14 over 3 is a fraction, which means it is relating a number of parts to the number of parts needed to make a whole. If you have 14 parts and it takes 3 parts to make a whole (think about pies or cakes that have been cut into 3 slices), then all you have to do is divide--if you have 14 parts and 3 of them make a whole, then you can use 12 of the parts to make 4 wholes, but you'll have 2 parts left over. So 14 over 3 as a mixed number is 4 2/3. (four and two-thirds)
