Whenever there is the same number in the numerator and the denominator, you can cancel both. If the numbers are different, but have a common factor, you can replace each number by its factors, and cancel some of the factors. When nothing is left on the top or on the bottom, you replace by the number 1 - one being the identity element of multiplication.
