Think money when ever you do percentages. It is the easiest way to calculate percentages. You will be able to do it fast and easy. So What is 25% of a $1.00 well in percentages it is out of 100 so 25% is the same thing as 25/100 or 1 quarter. So its 25. Now if you have $4 dollars what is 25%? Its simply 4 quarters or $1.00 (aka 100).

But a simple rule in percentages if you want to calculate ANY number all you do is times the 2 numbers and move the decimal 2 times to the left because 25% is .25 and if you times 25 you must adjust the decimal. So 25*400=10,000.00. Move the decimal 2 times and now your answer is 100.

Let, a is the 25 percent of 400

or, a=25% of 400 ;% means out of 100,so divide 25 by 100

or, a=25/100 X 400 ; of means multiply so put the sign of multiply

or, a=(25x400)/100 ;simplify

or, a=100 ;answer

Hence the required answer is 100, i.e. 25 percent of 400 is 100.
