Many food products, such as pies, pizzas, cakes and tarts are supplied as a large single item for subsequent subdivision by the end user.
Quite why this is so is mystifying to us - the obvious action is to sneak off with the entire pie and scoff it in secret.
However, to pander to the peculiar
predilections of you species, we suggest that such items are marked on their upper surface with a pattern of radial lines using UV ink. When illuminated with UV, this will disclose an inner ring of lines of originating at the centre, indicating cut positions for even fractions (1/4, 1/6, 1/8, 1/10) and around the circumference inward lines for the odd fractions (1/3, 1/5, 1/7)
One double width line runs from the centre to the circumference, representing the zero datum.

Yes, but then you'd have to go and find your UV lamp,
then realize the fuse in needs changing, then find a
way to hold the lamp in the right place while you cut
the pizza, then discover that you can't actually find
your pizza cutter... The whole thing would become
too protracted. |

// go and find your UV lamp // |
|
| |
Just use the UV illuminator mounted on the side of your head. |
|

// The whole thing would become too protracted. // |
|
| |
That's just your angle on it. |

The easiest way to cut a pizza into, say, three parts
is to first cut it in half, then cut one of the halves in
two for your guests. |
|
| |
But they are mutually exclusive... |

There is an interesting alternative proposal (on the link) and also a loveley book by Prof. Stewart headlining the topic. |

This is an awesome idea. Seeing the portions are
calculated electronically, you could devise non-symetrical,
wavy-lined odd shapes which are nevertheless of equal
area. |

or liquidise the pie & use a measuring jug? |
|

one cuts, the other chooses |
|

... bearing in mind that the one that cuts still has the knife. |

wow, during a previous century I thought that microwave ovens could read IR (nonvisble ink) patterns off the upper surfaces of food packaging, then customize beam strength that way the ice cream could remain frozen while the vegi-burger is warm! |

I like [Ian Tindales] idea of feeding bees with UV highlighted snacks though! |
