• 1/99999999999999

• It exists, but no one has discovered it yet.

• I don't know.

Why, when being added, must two fractions have the same denominator?

• It's mostly a matter of style...two fractions look better together when they have the same denominator.

• Because those are the rules, just like a card game, in order to "do math" you must play by the rules.

• Because, to add two numbers is to combine them and express this combination as a single number. So, two different fractions must each be expressed as some amount of the same fraction in order for their combination to be expressed as a single number.

• Because, like a tree or some aspect (or material) of nature...math has occurred, we don't understand it, but we must accept it because it's unchangeable and here forever. One of math's features is that fractions must have the same denominator when being added together.
