In order to do this sum (without using a calculator) you must find the lowest common multiple of 5 and 4.  It is 20.  This means that the bottom part of both fractions must become 20.  /20 + /20.  For the top half, you  must multiply the original top halves by what you multiplied the bottom halves.  1 X 4 = 4.  3 X 5 = 15.  The question now becomes:  4/20 + 15/ 20.  The answer is 19/ 20
