3 is 50% greater than 2
2 is 331/3% less than 3
To calculate a part-to-part ratio, you compare two different quantities by expressing them as a fraction. For example, if you have 3 apples and 2 oranges, the part-to-part ratio of apples to oranges is 3:2. This means for every 3 apples, there are 2 oranges. Ensure that the two quantities you are comparing are relevant to each other for the ratio to make sense.
Yes
You can not compare a square foot to a cubic foot because they are 2 different quantities!

Graphs compare quantities which are related to each other and are used to simplify or replace a written comparison of information
A ratio uses division to compare two quantities.
=, > or <.
Yes
The answer depends on what quantities you wish to compare. And, in a real world situation, it also depends on what tools you are capable of obtaining and using!

Yes, two probabilities.
to compare the two quantities
it reduces 3 AC quantities to 2 dc quantities rotating at the same speed about a fixed axis.
