Answer :
You have to find the least common denominator, which in this case would be 12.
8/12- 3/12= 5/12
8/12- 3/12= 5/12
Before you can add or subtract fractions, they must have a common denominator.
-- Find a common denominator for [ something/3 ] and [ something/4 ].
-- When you have both of the fractions changed to a common denominator, you can just subtract the second numerator from the first one, and write that difference over the same common denominator.
