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. Please help me to solve this problem. Thanks.
