Change the number into an improper fraction. Do you know how to do that?

For instance,
$$2\frac{1}{3} = \frac{7}{3}$$

i didn't no, but from the looks of it you multiply the whole number by the denominator and add the numerator

so i got it, much appreciated

Another way to think of it:

"Two and one-third" = $2+\frac{1}{3}$ ("and" typically means addition)

Think of a fraction with a denominator of 3 that is also equal to 2.

$$\frac{6}{3}+\frac{1}{3}=\frac{7}{3}$$

This is probably a bit more work than what's necessary, but I find it much more interesting.
