Simplify Fractions

 

 

 

To reduce a fraction, we must divide both the numerator and denominator by a number that goes into them both evenly.

4÷4=1

8÷4=2

4/8 reduced by 4 is 1/2

Reduce Fractions to lowest terms

A fraction is in lowest terms when the numerator and denominator have no common factor other than 1.

In order to work with fractions efficiently, it is important to reduce the fraction to lowest terms.

To reduce do the prime factorization. Write the numerator and denominator as a product of prime factors  and divide by the common factors.Reduce

 

 

 

The new fraction is still equivalent to the original fraction.
