- I think applying intuition based on dimensional analysis here will just serve to confuse rather than illuminate.
- $$\frac{1}{\frac{\text{berry}}{\text{apple}}}$$
would simply read as 1 over berry per apple but that itself does not have much intuitive meaning. It means that you are dividing 'dimensionless' 1 by berries per apples even though this is in the end equivalent to apples per berry ($\frac{\text{apple}}{\text{berry}})$. This is simply not useful representation of a relationship.Simply put not all representations of mathematical expressions are equally useful. Consider the following example:- $$y= 2x +10 \Leftrightarrow y-x -5 = x + 5 $$
- In the equation of line on the left we can clearly interpret 2 as the slope of the equation and 10 as an intercept of the equation.
In the equation on the right that is completely equivalent to the one on the left we cannot directly any of the numbers.
