You can put this solution on YOUR website! We are looking for percent.
Let p = percent
45 = p times 25
This can be expressed as 45 = 25p.
To find your percent, divide both sides by 25.
45/25 = p
1.8 = p
The answer is 1.8%
==============================================
The Proof:
Going back to your original question, if we multiply 25 by 1.8, we'll get 45 proving that 1.8% is correct.
