Reducing fractions, simplify, and reduce to the lowest terms all means to eliminate common factors}}} between the nominator and the denominator.
Definition: The greatest+common+factor or GCF
of two (or more) numbers is the product of all the factors the numbers+have+in+common.
If you wanted to find the greatest common factor of, for example,+24 and 36, you would express both as
products of their prime factors, and look for factors common to both:
24++=++2+%2A+2+%2A+2+%2A+3
36++=++2+%2A+2+%2A+3%2A3
There are two 2s and one 3 common to both numbers, so +2+%2A+2+%2A+3+=+12 is the " GFC " of 24 and 36.
once you have GFC, you divide the nominator and the denominator in order to reduce.
example:
24%2F36+=24%3A12%2F%2836%3A12%29=2%2F3
