Use this formula:
X= A*(1-P)
Where:
X= The answer
A= The initial value
P= The percentage to be subtracted

∙ 10y agoYou have to turn the percentage into a decimal.
A percentage is a portion of 100. so to find the calculation of a decreased percentage, you subtract.
U divide the percentage by the number. So .12/375=45
In order to find the percentage increase and decrease between to numbers are easy. All you have to is subtract the number you start out with to the number it becomes.
The number from which you subtract is called the minuend.

Second Number / First Number provides the second number as a percentage of the first. If there is an increase, simply subtract 1 from the result, and multiply by 100. If you do not multiply by 100, you are left with the result in decimal format.
You will get zero if you subtract a number from itself.
Subtract the subtrahend from the minuend to get the difference.
Use the percentage off multiplied by the amount. Subtract the number that you derived by multiplying the base price.
You subtract the smaller number from the larger, then divide the result by the larger number and multiply that result by 100.
You would subtract the atomic number from the mass number.
You take the original number. You then work out by how much this number has changed (so if the new number is bigger subtract the original number from the new number and if it is smaller subtract the new number from the original). Now you divide the difference (how much the number has changed) by the original number and multiply the result by 100.An example:100 becomes 120.The number has changed by (120 - 100) 20. It has increased by 20.To calculate the percentage change we do:20 (the change) / 100 (the original number) and then multiply by 100 (to turn it in to a percentage rather than a fraction).20/100 * 100 = 20%So, in this example, the number has increased by 20%.
