What is a percentage?

We are used to hearing the word percentage since our childhood but do we really know what a percentage is?

According to Wikipedia,

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign %, or the abbreviations pct. Sometimes the abbreviation "pc" is also used to denote percentage.

In the opinion of Merriam-Webster,

“A percentage is a part of a whole expressed in hundredths.

To understand the percentage, suppose you have pizza in front of you. You first cut the pizza in four slices and then further cut it to make a total of eight slices. Now, if you pick up one slice, you are holding some percentage of pizza in your hand.

It means that percentage is actually a part of a whole amount of something.

A discussed above, there are numerous formulas to calculate the percentage. We can use any of them depending on the type of percentage we want to calculate. Let’s find out step by step method to get a percentage.

  • Identify and write down the values.
  • Write down the percentage formula.
  • Substitute the values in the percentage equation.
  • Calculate the percentage by solving the equation.

If you need to calculate the increase in percentage, use our percentage increase calculator or percentage difference calculator.

Let’s go through an example to properly understand the percent calculations.

Example 1 – Find the percentage

Calculate the percentage if a college student has obtained 700 marks out of 1200 in exams.


Step 1: Identify and write down the values.

Part = 700, Whole = 1200

Step 2: Write down the percentage formula.

Percentage = (Part × 100) / Whole

Step 3: Substitute the values in the percentage equation.

Percentage = (700 × 100) / 1200

Step 4: Calculate the percentage by solving the equation.

Percentage = 70000 / 1200

Percentage = 58.33%

So, a student with 700 marks out of 1200 got 58.33% in exams.

Example 2 – Find the part

What is 20% of $800?


Step 1: Identify and write down the values.

Percentage = 20%, Whole = $800

Step 2: Write down the percentage formula.

Part = (Percentage × Whole) / 100

Step 3: Substitute the values in the percentage equation.

Part = (20 × 800) / 100

Step 4: Calculate the percentage by solving the equation.

Part = 16000 / 100

Part = $160

So, 20% of $800 is $160.

Example 3 – Find whole

$10 is 30% of what?


Step 1: Identify and write down the values.

Percentage = 30%, Part = $10

Step 2: Write down the percentage formula.

Whole = (Part / Percentage) × 100

Step 3: Substitute the values in the percentage equation.

Whole = (10 / 30) × 100

Step 4: Calculate the percentage by solving the equation.

Whole = 0.33 × 100

Whole = $33

So, $10 is 30% of $33.

  • Multiply the part with 100.

200 × 100 = 20000

  • Divide the amount by the whole amount.

20000 / 800 = 25%

What is a 5th of 100?
