Take the number and multiply it by 0.25 (which is equal to 25%). Then subtract that answer from the original number.
Ex:
25% off $200
200 x 0.25 = 50
200-50-150
$150

Discounts represents the amount of money you save. 25% means you save 25% of the initial price. If you want to calculate how much money you save, just multiply price and discount. If you buy a 16$ CD with a discount of 25% it means you save 25% of 16$ = 16*25/100 = 4$ and pay 16$-4$ = 12$.
If you are not interested in how much you save, but only in the final price, you can do like this: calculate 100%-discount and multiply the result for the price. If the discount is the money you don't pay, 100%-discount is the money you do pay. In the previous example, you pay 100%-25% = 75% of the original price, that is 75% of 16$ = 16*75/100 = 12$.

To calculate the discount, first multiply the original price by the percentage (to convert the percentage, move the decimal point to the left wo places, so 25% becomes .25, 15% is .15, 5% is .05). Then subtract that number from the original full price to get your discount.
So for a shirt that was originally $20, but is on sale for 10% off, you calculate it this way:
$20 (.10) = $2.
$20-$2=$18
The new price of the shirt with the discount is $18.

To see discounts of X% (either 25%, 15%, or anything else) simply multiply the price by 25% and subtract the result from the price.

If you get 25% off, then you will be paying 75% of the original value of an item. So to figure out the final price, take the original price times .75 (75% represented as a decimal).
Likewise if you get 15% off, you will be paying 85% of the original value of the item, so multiply the original price by .85.
In general, if you get n% off, multiply the original price by (100-n)% converted into a decimal.

I found a helpful website for math problems.
It is www.webmath.com
The site solves problems and explains how it did it. It takes about as long to find the site as it does to type in a question here. Check it out.

Find 10% of the number then half the 10% to get the extra 5% needed and add them together
E.G
15% of 74
10% of 74 = 7.4
5% of 7.4 = 3.7
7.4 + 3.7 = 11.1
