Equivalent Fractions
- are equal fractions.
Two fractions are equivalent if they represent the same amount.
Although the numbers may look different, calculations will show that
equivalent fractions are equal, or are the same fractions.
If a pizza is divided into 8 equal slices, and you get 4 of the 8 slices,
then it is the same as receiving half.
This just means that the same pizza was divided into 2, and you got 1 of the
2 portions which is half.

(Create) |
You can
create an equivalent fraction,
by multiplying the numerator and the denominator of a fraction by the same
number, or dividing the numerator and the denominator of a fraction by the
same factor.
To create
or find equivalent fractions it is important to know the
prime
factors of both the numerator
and the denominator.
You can use any of the two methods shown in the diagram below to find the
prime factorization of a number.

You can use prime factors of both the
numerator and the denominator to determine equivalent fractions, as well as
to simplify fractions.
In the example the fraction 4/12 is simplified forming a new equivalent
fraction 1/3.
Steps
To Simplify Fractions:
(1) Find the prime factors of both the numerator and the denominator.
(2) Cancel out all common factors.

Whenever an equivalent fraction is needed
with larger numbers in the numerator and the denominator, we build the
fraction or express the fraction in higher terms.
Steps
For Expressing A Fraction In Higher Terms:
(1) Multiply the numerator by any required number.
(2) Multiply the denominator by that same number.
Note: According to the Fundamental Properties Of Fractions, the resulting
fraction has the same value and is therefore an equivalent fraction.
