The common denominator of any two or more whole numbers will always be 1.
since 12"X12" is inches, we convert that to feet meaning 1'X1' 238 sq feet of floor is the same as 238 tiles at 1 sq ft each. I assume that the 12 before 12X12 in your question is how many tiles in a box. You will need to divide 238 by the number of tiles per box. So 238/12 is how you get the to the final answer; 19.8 boxes. We round UP to the next nearest box to cover breakages and funny cuts.
