How to calculate 10 percent of an amount
For find out 10 percent of a number we only have to apply a simple rule of three:
In this case, the two unknowns of which we do not yet know the value are the following:
- B: Number from which we want to calculate its 10%
- We still need to know the value of 'Y', a number that will represent 10 percent of the initial number.
Applying the rule of three we can clear the value we are interested in as follows:
Y = quantity x 10 / 100 = quantity x 0.1
In short, to take 10 percent of something we have to multiply the number by 0.1. To make it clearer, we will now see how the above applies to a practical example.
Calculate 10 percent of 1000
To find the 10% of the number 1000, we will use the formula we have seen above:
Y = = = quantity x 0.1 = 1000 x 0.1 = 100
As you can see, it is very easy calculate 10 percent of any number with a simple multiplication. Remember that multiplying by 0.1 is the same as dividing by 10, that is, you have to move the decimal point one place to the left. Surely this trick will allow you to calculate the percentage from memory and without the need for calculators.
Calculate the 10 percent increase
So far we have seen how to calculate the 10% of an amount, but what if we want to calculate that percentage increase?
In that case all we have to do is to add to the initial amount its 10%. For example, let's calculate the 10 percent increase of 100:
10% increase = initial quantity x 0.1 + initial quantity = 100 x 0.1 + 100 = 110
Calculate 10 percent less
If what we want is to subtract from a quantity its 10%, in that case the formula we will have to use will be the following:
10% minus = initial quantity - initial quantity x 0.1
For example, if we want to subtract 10% from 500, it would look like this:
500 - 500 x 0,1 = 500 - 50 = 450
