Jon made 2 pans of cornbread that were exactly the same size. He cut the first pan into 8 equal pieces. He cut the second pan into 12 equal pieces. He gave  $\frac{2}{8}$   of the first pan of cornbread to his uncle. He gave  $\frac{3}{12}$    of the second pan of cornbread to his next door neighbor. Jon’s little sister, Maya, said it wasn’t fair because the next door neighbor got more cornbread than their uncle. Jon said they got exactly the same amount of cornbread.

Who was right, Jon or Maya?

• Jon

• Maya

• Neither

• Both

Xavier ate one-half of a mini-pizza. Justin ate one-fourth of a giant pizza. Their friend, Amber, said that Xavier ate more pizza than Justin because a half is always more than a fourth.

Do you agree with Amber?

• Yes because one half is larger than one fourth

• No because the pizza are different sizes so you can't compare them.

• Yes because one fourth of a giant pizza is more than one half of a mini pizza.
