The least common denominator of fractions is the least common multiple of their denominators. The least common multiple of 5 and 4 is their product (20), because they have no common factors. You need to rename each fraction using 20 as a denominator.

To find the numerator, multiply each fraction by 20.
  3/5*20 = 60/5 = 12
  1/4*20 = 20/4 = 5

Your fractions are
  3/5 = 12/20    (this is equivalent to (3/5)*(4/4))
  1/4 = 5/20    (this is equivalent to (1/4)*(5/5))
