5/8 - 1/4 = 5/8 - 2/8 = 3/8 (make all fractions equivalent fractions with a common denominator - in this case, a common denominator of 8 - and then subtract the numerators).
The reciprocal of 1 over 4 is 4 over 1. To get the reciprocal the numerator becomes the denominator and the denominator becomes the numerator.
The common denominator of any two or more whole numbers will always be 1.
Both of those fractions are in their simplest form, which means they have a GCF of 1. The least common denominator is 20.
20 is the lowest common denominator for 4 and 10.
