Most people want to learn basic math, but they might face some problems during the solution. When you know the authentic guidelines and formulas of basic math, then you can do any question within a short period. Do you want to know about Subtracting Percent Calculator? If yes, then we will give you an authentic and easy solution for this math problem. All you need to do is remember the formulas and guidelines, so it will help you to calculate subtracting any percentage from the amount you want to choose. So, let’s get into the further details!

## How to subtract percentages using a calculator?

1. Enter the total amount of value from which you want to subtract such as 20% on your calculator. Let’s assume, the total value is \$85.50.

2. Then in the next step, you need to press the multiplication button x on your desired calculator.

3. In the next step, you need to enter “0.8” which represents the 80 percent, then you need to hit the equal button on your calculator.

Example:

\$85.50 x 0.8, which is equal to \$68.40.

## 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.

### 1. What is 39 minus 80%?

Answer. To subtract 80% from the number 39, you need to just divide the percentage by 100, then subtract this number value from 1, and then multiply it with the initial value (39),

Final Value = 39 x (1 – 80/100)

Final Value = 39 x (1 – 0.8)

Final Value = 39 x (0.2)

Finally, you will get 7.8 as a final result.

### 2. How I can easily subtract percentages?

Answer. It is not a difficult task for you when you know completely know the basic procedure of subtraction. If you want to subtract any percentage from the desired number, you only need to multiply that specific number by the percentage which you want to remain. In simple words, you can multiply it by 100% minus the percentage which you want to subtract in the format of the decimal.
