How do you subtract improper fraction?

If the denominators (bottom numbers) are the same (eg. 11/6 - 7/6) you just subtract the numerators (top numbers) eg. 11-7=4 so 4/6. If the denominators are different you have to find equivalent fractions where the denominators are the same.

Find the least common denominator and convert them to equivalent fractions so that the denominators are the same. Choose the one with the greatest denominator.


Can you add numbers with different numerators?

Yes, 'fractions' with different numerators can be added, but not with different denominators. In the case where you have different denominators, you must find the LCM (lowest common multiple).
