3/15 + 12/18 = ???

To add (or subtract) fractions a common denominator needs to be found. This is usually the lowest common multiple of the present denominators but if this cannot be easily calculated use the product of the present denominators. The LCM of 15 & 18 is 90.

3/15 = 3x6/15x6 = 18/90 : 12/18 = 12x5/18x5 = 60/90

Then 18/90 + 60/90 = 18+60/90 = 78/90 which can be simplified to 39/45
