Find the greatest common factor between the numerator and the denominator, then divide the numerator by greatest common factor and then divide denominator by greatest common factor, for a new simplified fraction.

simplest form

Divide numerator and denominator by their greatest common factor.

By factoring the numerator and denominator in a fraction, you can then divide common multiples out and reduce the fraction to the simplest terms. Perhaps an example might be of help. If we have 66/99, we can see that 66 = 2 x 3 x 11, and 99 = 3 x 3 x 11. We can divide the 3 and the 11 out of both the numerator and denominator, and have 2/3 as the answer. The 66/99 = 2/3. Factoring the numerator and denominator allow us to see what we can divide out to reduce the fraction.

Find the GCF of the numerator and the denominator and divide them both by it. If the GCF is 1, the fraction is in its simplest form.

When a fraction is simplified, it is made into an equivalent fraction with no common divisor between the numerator and denominator.

It is called reducing or simplifying the fraction.

To simplify a fraction, divide the numerator and the denominator by their GCF.Example: 30/42The GCF of 30 and 42 is 6.6 into 30 is 56 into 42 is 730/42 = 5/7

When a the GCF of the numerator and denominator of a fraction is 1, the fraction is in its simplest form.

Find the Greatest Common Factor (GCF) between the numerator and denominator, then divide the numerator by GCF and denominator by GCF to get the new numerator and denominator. If the GCF is 1, then the fraction is already simplified. Example: 6/9 --> The GCF is 3, so 6/3= 2 and 9/3 =3, so the new simplified fraction is 2/3.

A fraction where the numerator and denominator have a GCF of 1 is said to be in its simplest form.
