Well, actually there are an infinite number of them,
and I'm kinda busy right now.
Here are a few:
2/6, 3/9, 4/12, 5/15, 6/18, 7/21, 8/24, 9/27, 10/30, 11/33, 12/36,
13/39, 14/42, 15/45, 16/48, 17/51, 18/54, 19/57, 20/60, 21/63, 22/66,
23/69, 24/72, 25/75, 26/78, 27/81, 28/84, 29/87, 30/90, 31/93, 32/96,
33/99, 34/102, 792/2376.
You can make them yourself, any time you want, as many as you want.
Here's how:
-- Pick a number, any number. Write it on top of the fraction.
-- Multiply your number by 3 . Write it on the bottom of the fraction.
There you have it . . . another fraction equivalent to one-third,
and YOU wrote it.
