Fractions<br />

For example:<br />

• 2 is half of 4 and 1 is half of 2 and 50 is half of 100.<br />

2 1 50<br />

4 2 100<br />

• All these fractions are equal to 1/2 (one-half) because they describe the<br />

same thing in different ways. They are equivalent fractions.<br />

To find if fractions are equivalent, you cross-multiply.<br />

1. Take the first numerator and multiply it by the second denominator.<br />

2. Next take the first denominator and multiply it by the second numerator.<br />

For example: Are and equivalent fractions<br />

• 1 x 12= 12 3 x 4= 12 Yes, they are equivalent fractions.<br />

To rename equivalent fractions you multiply or divide both the numerator and<br />

denominator by the same number. This does not change the value of the fraction<br />

because you are multiplying or dividing by 1. 1 can be shown as 1/1, 2/2, 3/3, 4/4<br />

and on.<br />

For example: Write 3 fractions equivalent to .<br />
