will be a "difference" problem.
First, in order to find the difference between the two, you need to find a common denominator.
In this case, 6 and 4 are your denominators. You must find a common multiple of these factors. For example,
4*3=12
and
6*2=12
therefore, you can see that 12 is a common multiple of each number.
