Is there an example to demonstrate why $\frac{1}{\left(1/2\right)}$ equals 2?

I know you are looking for something about pizzas but I think fractions in general work better if you work with a definition more akin to the axiomatic definition.
I mean what is $\frac{1}{\pi }$ in terms of pizzas?
I would define $\frac{1}{x}$ as the number, which when multiplied by x, gives me 1. This works fine for pizzas because, e.g. $2×\frac{1}{2}=1$ two half slices is the whole.
Now whatever $\frac{1}{\frac{1}{2}}$ is, if I multiply it by $\frac{1}{2}$ I get one so that
$\frac{1}{\frac{1}{2}}\cdot \frac{1}{2}=1...$
but this is nothing other than two... (or multiply both sides of the equation on the left by two).

Use ratios.
Pizza will be consumed at a rate of one person per one-half pizza.

Pizza is delivered at a rate of 1 pizza per day

To avoid an excess of pizza, we require at least
