How it is used
To add or subtract fractions you need a common denominator, ideally the lowest common denominator. A denominator can never be zero, which is why some values are excluded from a function's domain.
Example sentences
Find a common denominator before you add 2/3 and 3/4.
The denominator is zero when x = 5, so the function is undefined there.
Common collocations
