Possible diagram:

It is important that the whole be the same for both fractions so that when divided into 8 equal pieces, a one-eighth piece will be smaller than a piece from a whole divided into four pieces.

AA. Confused!

On planet Zimbo, a Zimbonese was told that the number 8 was larger than the number 4. But now there is confusion because the Zimbonese has also been told that 1/8 is smaller than 1/4. Please use a diagram to explain why 1/8 is smaller than 1/4.
