## How to calculate 100 Minus 10%?

To subtract the percentage from any given number, you only need to remember this formula:

Final Value= Initial Value – %/100 x Initial Value

With the following step, you can easily solve this example,

#### Step 1:

Replace the initial value (100) and also the percentage which you want to subtract (10) in the given formula:

Initial Value = 100

Percentage = 10

Final Value = 100 (10/100 x 100)

#### Step 2:

Then in this second step, you need to divide the percentage (10) by 100, after this step you will get the percentage in the format of the decimal. Also, you can do this step by just moving the 2 decimal places to the left side.

Final Value = 100 – (0.1 x 100)

#### Step 3:

Then, you need to multiply the percentage in the form of decimal (0.1) by the initial value (100),

Final Value = 100 – 10

#### Step 4:

Finally, you need to subtract the recent result (10) from the initial value (100) to get the final result value, which is 90.

## What is the percentage difference formula?

#### Formula:

Percentage Difference = | V1 – V2| / (V1 + V2)/2 * 100

#### Example:

|10 – 6| / (10 + 6)/2

Which is equal to = 4/8

Finally, you will get 0.5, as a 50% in percentage result.
