How to subtract percentage from a number

Subtracting a percentage from a number is a simple process that helps you find the reduced value. Let's learn how to do it step by step!

Step 1: Understand What Subtracting a Percentage Means

When you subtract a percentage from a number, you are reducing that number by a certain portion of itself. It's like applying a discount to a price!

Step 2: Gather Your Numbers

To begin, you'll need two things: the original number and the percentage you want to subtract. For example:

  • Original Number: 200
  • Percentage to Subtract: 15%

Step 3: Convert the Percentage to a Decimal

To work with percentages in calculations, convert the percentage to a decimal by dividing by 100:

Decimal=Percentage / 100

In this example: Decimal=15 / 100=0.15

Step 4: Multiply the Original Number by the Decimal

Now, multiply the original number by the decimal to find the amount to subtract:

Amount to Subtract=Original Number × Decimal

In our example: Amount to Subtract=200 × 0.15=30

Step 5: Subtract the Amount from the Original Number

Finally, subtract the calculated amount from the original number to find the new, reduced value:

New Value=Original Number - Amount to Subtract

In this case: New Value=200 - 30=170

Let's Recap:

  • Subtracting a Percentage reduces the original number by a certain portion.
  • Gather Your Numbers: The original number and the percentage to subtract.
  • Convert to Decimal: Divide the percentage by 100.
  • Multiply the Original Number by the Decimal to find the amount to subtract.
  • Subtract the Amount from the original number to get the reduced value.
