To find equivalent fractions, you can multiply or divide the original fraction by another fraction that equals 1, such as using the same number as both the numerator and denominator, according to the identity principle. Common mistakes include thinking fractions are equivalent only if they have the same numerator, but fractions can be equivalent even if they appear different.

1. How do you find an equivalent fraction?

2. In this lesson you will learn how
to find equivalent fractions by
using the identity principle.

3. A common mistake is…
Thinking that fractions are equivalent
because they have the same numerator.

4. Let’s Review
Fractions that look different can be
equivalent (have the same value)

5. The Identity Principle
If you multiply or divide any number by 1,
you get the same number.
3x1=3 3_1=3

6. This also works for fractions.

7. 1 can also be a fraction. When the numerator
and denominator are the same, the fraction
equals 1.
=1 =1 =1

8. What if we multiplied or divided a fraction
by a fraction that equaled one?

to find equivalent fractions by
