2. What are
Equivalent Fractions?
• Fractions that are equal. The number of
equal pieces are different, but the fraction’s
value (out of the whole) is the same.
• As an example, think of a two-slice pizza that has
then been cut into four slices, six slices, etc. The
size of the original pizza hasn’t changed!

In other words, 1/12 is smaller than 1/6,
so 11/12 is the larger fraction.
