How to add percentage to a number

Adding a percentage to a number is easy and useful for finding an increased value. Let's learn how to do it step by step!

Step 1: Understand What Adding a Percentage Means

When you add a percentage to a number, you're increasing that number by a certain portion of itself. It's like applying a markup to a product price!

Step 2: Gather Your Numbers

You'll need two things: the original number and the percentage you want to add. For example:

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

Step 3: Convert the Percentage to a Decimal

To use 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

Next, multiply the original number by the decimal to find the amount to add:

Amount to Add=Original Number × Decimal

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

Step 5: Add the Amount to the Original Number

Finally, add the calculated amount to the original number to find the new, increased value:

New Value=Original Number + Amount to Add

In this case: New Value=200 + 30=230

Let's Recap:

  • Adding a Percentage increases the original number by a certain portion.
  • Gather Your Numbers: The original number and the percentage to add.
  • Convert to Decimal: Divide the percentage by 100.
  • Multiply the Original Number by the Decimal to find the amount to add.
  • Add the Amount to the original number to get the increased value.
