The / works well for over (except for radio commo)

The 3 terms have to have the same denominator to be combined, called "common denominator" The product of the denominators (regardless of the # of terms) always works. 7*4*2 = 56. But for this one, it's easy to spot that 2 is a factor of 4, and use 7*4 instead.
