# Common Denominator Cupcakes

What do fractions and these delicious cupcakes have in common? Well, for one thing, they both are a ‘whole’ lot of fun!

Here’s a question: One day a rabbit came and munched on ¼ of Leeza’s garden. Another rabbit came along and chomped through 2/4 of the garden. How much of the garden did these bustling bunnies eat altogether?

(What’s the common denominator—number on the bottom—in the number sentence ¼ + 2/4? That’s right, it’s fur… er, four!)

When ADDING fractions, the denominator stays the same. That’s because the denominator is the marker, or kind of fraction you are adding. So, ONE fourth plus TWO fourths equals… THREE fourths.

Adding fractions is a piece of cake!
