📊💯Have you ever seen a sale sign that says “50% off” or heard someone say they scored 90% on a test? These numbers use percentages. A percentage tells us how many parts we have out of 100. Percentages help us compare numbers easily and understand parts of a whole.
The word percent means “per hundred.”
The symbol for percent is %.
Example:
25%
This means 25 out of 100.
Percentages are another way to represent fractions and decimals.
Example
| Fraction | Decimal | Percent |
|---|---|---|
| 1/2 | 0.5 | 50% |
| 1/4 | 0.25 | 25% |
| 3/4 | 0.75 | 75% |
A percentage shows how much of something there is out of 100.
For example:
If 100 students take a test and 80 pass, then:
80% passed the test.
This means 80 out of 100 students passed.
Fractions can be turned into percentages.
Example:
1/2
First convert it to a decimal:
1 ÷ 2 = 0.5
Then multiply by 100.
\text{Percent} = \text{Decimal} \times 100
So:
0.5 × 100 = 50%
Percentages are used in many everyday situations.
Test Scores
If a student answers 18 out of 20 questions correctly, their score might be 90%.
Shopping Discounts
A store offers 20% off a toy.
This means the price is reduced by 20 out of every 100 parts of the price.
Battery Level
Your phone battery might say 75%, meaning 75 out of 100 parts of the battery are full.
