EQUIVALENT FRACTIONS
Equivalent Fractions have the same value, even though they may look different.
These fractions are really the same:
12 = 24 = 48
Why are they the same? Because when you multiply or divide both the top and bottom by the same number, the fraction keeps it's value.
The rule to remember is:
"Change the bottom using multiply or divide,
And the same to the top must be applied

What is a Common Denominator?When the denominators of two or more fractions are the same, they are Common Denominators.
