EQUIVALENT FRACTIONS

• a fraction that is the same as another fraction but with a different denominator

• We can multiply or divide to find equivalent fractions.

 $\frac{2}{4\ }=\ \frac{?}{2}$                     ? = 1                   

To move from "4" to "2", we must divide.  4  $\div$  what number = 2?  __
Whatever we do to the denominators, we must do to the numerators.
So, 2  $\div$  2 = 1.

 $\frac{?}{4}=\frac{2}{8}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ?\ =\ 1$  

When our number gets bigger, we must multiply.
4 x what number = 8? _____
So, we must ask ourselves, "? x 2 = 2"
The answer is 1 x 2 = 2

 $\frac{1}{2}$  =  $\frac{?}{6}$                  ? = 3

To move from "2 to 6", we must multiply.  2 x what number = 6? __
Whatever we do to the denominators, we must do to the numerators.
So, if 2 x 3 = 6, what is 1 x 3?
