Equivalent Fractions
Find equivalent fractions.
Write fractions in simplest form.
Test the equality of two fractions.
Read a US Ruler.
Let’s start this section by answering an important question: When are two fractions equal? Two
fractions are equal when they represent the same part of a whole!
Equivalent Fractions: Two fractions are equivalent if they are represent the same part of a
whole.
Ex. 1, pg. 201
Ex. 2, pg. 202
Now let’s look at the mathematics behind equivalent fractions. We use multiplication to find equivalent
fractions. Notice that both the numerator and the denominator were multiplied by the same factor.

Section 2.6
Multiplying and Simplifying Fractions
Overview:
 Multiply and simplify fractions.
 Simplify fractions which have addition and subtraction in the numerators or denominators.
 Compare fractions using the symbols <, >, and =.

Ex. 3, pg. 221
Ex. 4, pg. 222

Just like whole numbers, we can compare fractions using the following symbols:
 <
“is less than”
 >
“is greater than”
 =
“is equal to”
When comparing fractions we will look at two different methods, the first is using fraction bars.
Ex. 5, pg. 224
Ex. 6, pg. 224
Let’s look at another method for comparing fractions which involves using equivalent fractions. The idea
is if we can cleverly change each fraction to the same denominator, we’ll be able to compare the
numerators and easily see which fraction is larger.
Ex. 7, pg. 225
Ex. 8, pg. 226
