What are common fractions?

When the numerator is less than the denominator then it is a common fraction but if the numerator is greater than the denominator then it is an improper fraction.


When a fraction cannot be simplified what must be true about the greatest common factor of the numerator and denominator?

It is 1.


What is the greatest common factor of any fraction in lowest terms?

1 is the greatest common factor of any fraction in lowest terms.


What do you do to the numerator in a lowest common denominator problem?

Multiply the numerator of the fraction by the same amount that you multiply the denominator of that fraction.


Describe how finding the greatest common factor of the numerator and denominator of a fraction can help reduce the fraction?

5/7 is a fraction in its simplest form. To create an equivalent fraction it is necessary to multiply both the numerator and the denominator by the same integer. The opposite is also true. To reduce an equivalent fraction to its simplest form, it is necessary to divide both the numerator and the denominator by the same integer. 20/28 is an equivalent fraction of 5/7. It is possible to reduce 20/28 to 10/14 by dividing both the numerator and the denominator by 2, but that is not the simplest form. 10/14 can be reduced to 5/7 by dividing both the numerator and the denominator by 2 again. To ensure that an equivalent fraction is reduced to its simplest form, it is necessary to divide by the largest factor that is part of both of them. Another term for this the Greatest Common Factor, or GCF.

How do you know if a fraction is simplified?

A fraction is considered simplified or reduced when the numerator and denominator have no common factors other than 1. In other words, there is no integer greater than 1 that divides evenly into both the numerator and the denominator. If there are common factors, the fraction can be simplified further by dividing both the numerator and denominator by their greatest common factor.
