Quickly - Is 15% of 20 the same as 20% of 15?

Answer:

Yes.......the answer to both is 3. 

Now, answer this question:

Which is larger?

94.1% of 23.25 or
23.25% of 94.1?

Answer:

They are equal - it is the same type of problem as the first example. 

A% of B will always equal B% of A, since the former equals A/100 times B (or AB/100) and the latter is BA/100.
