“How to calculate percentage”

Percentages might feel like mysterious math magic, but worry not! They’re actually quite simple once you break them down. This blog will guide you through calculating percentages in clear, bite-sized steps.

What is a percentage?

Consider a percentage to be an elegant way of expressing “out of 100.” It’s comparable to telling someone how many equal slices you have after dividing something into 100. 50% therefore indicates that you have 50 of the 100 slices.

The Basic Formula:

There’s a handy formula for calculating percentages:

(Part you want to find the percentage of) / (Whole thing) x 100

Let’s break it down:

• Part you want to find the percentage of: This is the smaller number you’re interested in.
• The whole thing: This is the bigger number, representing the entire group or context.
• 100: This is the magic number that makes everything a percentage.

Simple Steps to Calculate:

1. Identify the “part” and “whole.” What are you trying to find the percentage of, and what’s the bigger context?
2. Plug them into the formula. Write down the “part” number, then divide it by the “whole” number.
3. Multiply by 100. Don’t forget this crucial step to turn your decimal into a percentage!
4. Voila! You have your percentage. Write it down with the % symbol.

Examples:

• What percentage of 80 apples are rotten? Let’s say 16 are rotten.
  • Part = 16, Whole = 80
  • (16 / 80) x 100 = 20%
• You scored 75 on a 100-point test. What’s your percentage?
  • Part = 75, Whole = 100
  • (75 / 100) x 100 = 75%

Bonus Tips:

Percentages can also be used to identify components of a whole. For instance, how many of the thirty students in a class, if 60% of them have blue eyes, have blue eyes? To get the part, just flip the formula: (Percentage / 100) x Whole.

Remember, percentages can be used for anything, not just numbers! You can find percentages of distances, areas, times, and more.

With these simple steps and a little practice, you’ll be a percentage pro in no time! Go forth and conquer those calculations!
