The Honest Page
Which parts of this story are true, stretched or made up?
True
- Sixty-three centimetres shared by seven is 9 centimetres, and a seventh of a full turn is about 51.4 degrees.
- A seventh is a little bigger than an eighth and a little smaller than a sixth: the more equal pieces, the smaller each one.
- Sevenths really are awkward: a perfect seven-sided shape cannot be drawn with only a compass and a straight edge. Source
Stretched
- The strip of paper round the tin gives seven exactly equal slices. What we simplified: Marks on the edge give equal slices only if every cut goes through the very middle; real cuts wobble a little.
Made up
- The community kitchen, the seven guests and the plum pie are made up. Halver, Pie and Liner come from FractionForge, and Bà Tư from VanTots.
