Simple Example

Quick Example

Imagine your favourite cricket team scored 100 runs in a match. If the coach says, 'The team achieved 100% of their target score for today!' it means they reached the full target. As a fraction, this means they completed 1/1 of their target.

Worked Example

Step-by-Step

Let's convert 100% to a fraction.

Step 1: Understand that 'percent' means 'out of 100'. So, 100% means 100 out of 100.
---Step 2: Write this as a fraction: 100/100.
---Step 3: Simplify the fraction. Both the numerator (top number) and the denominator (bottom number) are 100.
---Step 4: Divide the numerator by the denominator: 100 ÷ 100 = 1.
---Step 5: So, 100% as a fraction is 1/1, which simplifies to 1.
