Find the Greatest Common Factor (GCF) of 12 and 15,If it exists, and by dividing both the numerator and denominator by it, reduce our fraction. GCF = 3, and our simplified answer
To get the answer, find the GCF (greatest common factor) of the numerator and the denominator. Once you have the GCF, divide the 12 and 15 by that number. Here, the GCF is 3.
