Simplying fraction

If we simplify a fraction, then we are reducing it to lowest terms. Reducing a fraction to lowest terms will not change its value; the reduced fraction will be an equivalent fraction. All we need to do is divide the numerator and the denominator by the same nonzero whole number.

For example

In the example above what they do to arrive at the answer is to continue to divide both the numerators and the denominators by 2 until it cannot go any further.
