Remember that "percent" means "of one hundred"
So, 25% is the same as 25/100. If you were divide a number (like 25) by 100, all you do is move the decimal two places to the left.
So, 25 will become 0.25.
Now, just multiply 400 x .25 = 100.
Let's see some more.
37% of 45. Just move that decimal. 45 x .37 = 16.65
This even works for small numbers!
3% of 200.
Move the decimal...3% becomes .03
So .03 x 200 = 6.
Hope that helped.

convert the percent into a fraction and multiply that fraction by the number
ex. 25% = 1/4
so, 1/4 * 400 = 100
or, you could just change the percentage into a decimal by moving it to the left two places and multiply it by your number
ex. 25% = .25
and, .25 * 200 = 100

lets say you need 125% of a #. You multiply the number by 1.25. If you need 45%, you multiply by .45. Get it?
