Some time ago, I posted a fractions puzzle involving flat bread. You can read about it here. Here’s the question – if I take a flat piece of bread, and give you half, then you give me back a quarter, then I give you back an eighth, and you give me back 1/16, and so on ad infinitum, how much of the original flat bread do I have?
I have four different things I can spread on my toast. If I want to taste them all, I need four slices of toast.
For those of you who don’t know what a bagel is, it’s a bun with a hole in the middle. A doughnut made out of bread dough. If you can’t get hold of a bagel for the puzzle on this page, use a doughnut instead.
