To reduce a fraction means to remove a common
factor that the
numerator and the
denominator both have.
This means that you have to factor both the numerator and denominator

Multiply the remaining numbers (after you cancel the common factor in the numerator) in the denominator together to get the new denominator.

||Remove the 3's and you get 2/3|
|Here's another example:|
||Remove the 7's and you get 3/4
Now here's a problem for you. Reduce this fraction:
