What fraction is equivalent to 1/3

It can be any kind of fraction, the possibilities are endless. So what you do is multiply it by one. I know that sounds kind of wrong, but you'll see. So you know that because of one rule (I forget the name, I'll get back to you on that one) But it says that one can be expressed as a fraction, which allows you to create an equivalent fraction. For example 2/3 x 3/3 = 6/9, simplified = 2/3.

3/9 is equivalent to 1/3 if we multiply both of them by 3
