The is no "largest" common denominator. For any denominator you find, we can multiply it by a natural number and come up with a larger one.
Do you mean LEAST COMMON DENOMINATOR?

What is one fifth plus three fourths?
1/5 + 3/4 First you have to find the common Denominator. The common denominator is 20. 1/5 = 4/20 (5x4=20, so you have to multiply the 1 by 4 as well) 3/4=15/20 (4x5=20 and 3x5=15) Now that you know your common denominator is 20, you can now add your fractions. 4/20 + 15/20 = 19/20 (you only add the numerator, the denominator stays the same) so, your answer is...... 19/20
