# Comparison between 2 or more quantities

## Main Question or Discussion Point

Hi everyone, I need your help badly.

This may sound simple to everyone but I need to get the concept sorted out.

For ratios, we know that it is a comparison between 2 or more quantities with the same units.

My question is, can ratio be used to compare between say ingredients in a recipe? say 1 cake needs 5 eggs, 2 cakes needs 10 eggs. Thus 1:5 and 2:10.

Tecnically they are of different "units" (cakes to eggs) but it seems fine to me if we compare it in such manner.

Yes, that is true

Yes you can I believe.

You aren't comparing cakes to eggs in the sense that you are taking a cake and dividing it by 5 eggs.

You are comparing the Number of cakes to the number of eggs.
So the ratio of the number of cakes you can make to the number of eggs needed to make the cakes is given by 1:5
