Birthday cake, anyone?

This photo was taken by son. He needed a photo for his math homework, it needed to represent a fraction of something. So he asked if could have a slice from my birthday cake, a big slice, so that only half of the cake would remain for his homework picture. I told him, it was a great idea but perhaps we could all partake a slice, enough to get it to half way mark. He didn't seem as excited but he obliged and then took this photo.
