Best Answer

First, change it so that the two fractions have the same denominator (by changing the fractions into equivalent fractions).

Once the two fractions have the same denominator, it is simply a case of subtracting the numerators, leaving the denominator the same.

Finally, reduce the fraction to its lowest terms (if possible).
