Does Lili have more cookie than Lola?

Examine the following image.

A Persian cookie divided into pieces: On the left side of the image there is half of the cookie with a label underneath that says 1 half. On the right side of the image there are two quarters of the cookie with a label underneath that says 2 fourths.

Lola has half a cookie.

Lili broke her half into two equal pieces which we call fourths. We call them fourths because four of these pieces would make one whole cookie!

1 half is the same, or equal to, 2 fourths.
