What is it?

10% as a fraction means representing '10 parts out of every 100 parts' in the form of a fraction. A percentage is always 'out of 100', so 10% literally means 10/100.

Simple Example

Quick Example

Imagine you have 100 delicious ladoos in a box. If you eat 10% of them, it means you eat 10 out of the 100 ladoos. As a fraction, this would be 10/100 of the ladoos.

Worked Example

Step-by-Step

Let's convert 10% into a fraction.

Step 1: Understand that 'percent' means 'per hundred'. So, 10% means 10 out of 100.
---
Step 2: Write this as a fraction: 10/100.
---
Step 3: Now, simplify the fraction. Find a common number that can divide both the numerator (top number) and the denominator (bottom number).
---
Step 4: Both 10 and 100 can be divided by 10.
---
Step 5: Divide the numerator by 10: 10 ÷ 10 = 1.
---
Step 6: Divide the denominator by 10: 100 ÷ 10 = 10.

Step 7: The simplified fraction is 1/10.

So, 10% as a fraction is 1/10.

Common Mistakes

MISTAKE: Writing 10% as 10/1 | CORRECTION: Remember 'percent' means 'out of 100', so always use 100 as the denominator initially.

MISTAKE: Not simplifying the fraction, leaving it as 10/100 | CORRECTION: Always simplify fractions to their simplest form by dividing both numerator and denominator by their greatest common factor.

MISTAKE: Confusing 10% with 0.10 and thinking it's not a fraction | CORRECTION: 0.10 is the decimal form of 10%, which can also be written as 10/100, so it is indeed related to fractions.
