1. Using the diagram, you can write two equivalent fractions:
EXAMPLE 1
Identifying Equivalent Fractions
There are 10 fish in an aquarium, and 2 of them are goldfish. The fish in the aquarium are arranged in the diagram below. What fraction of the fish in the aquarium are goldfish?
SOLUTION
Using the diagram, you can write two equivalent fractions:

2. Number of groups of 2 goldfish Number of groups of 2 fish = 1 5
EXAMPLE 1
Identifying Equivalent Fractions
Number of goldfish
Number of fish = 2 10
Number of groups of 2 goldfish
Number of groups of 2 fish = 1 5
The fractions and are equivalent fractions because they represent the same part-to-whole relationship. 2 10 1 5

3. Write two fractions that are equivalent to 6 8 .
EXAMPLE 2
Writing Equivalent Fractions
Write two fractions that are equivalent to 6 8 .
To find equivalent fractions, multiply or divide the numerator and denominator by the same nonzero number. Because you are multiplying or dividing by 1, the value of the fraction does not change. 6 8 = 3 6 8 = 18 24
Multiply numerator and denominator by 3. 6 8 = 2 6 8 = 3 4
Divide numerator and denominator by 2, a common factor of 6 and 8.
ANSWER 18 24
and are equivalent to . 3 4 6 8
