Whimsical Frog NotePad

Notepads like this one make writing fun!

These are very happy looking frogs. Maybe it's because there are pretty flowers to look at and flies to eat.

So... a question: If the 2 frogs split the flies evenly between them, how many flies does each frog get to eat?

Size: (of the notepad, not the flies!) 5" x 7" , about 1/4" thick (75 sheets)
