Convert the fractions to equivalent fractions having the same denominator (this is usually the lowest common denominator). The fractions can then be subtracted by finding the difference of their numerators.
EXAMPLE : 5/6 - 3/4 : 5/6 is equivalent to 5x2/12 = 10/12: 3/4 is equivalent to 3x3/12 = 9/12
10/12 - 9/12 = 1/12.
