Step-by-Step Examples

Example 1: Convert 75%

75% = 75 ÷ 100 = 0.75

Or: Move decimal 2 left: 75. → 0.75

Example 2: Convert 125%

125% = 125 ÷ 100 = 1.25

Percentages over 100% give decimals greater than 1

Example 3: Convert 3.5%

3.5% = 3.5 ÷ 100 = 0.035

Works with decimal percentages too!

Example 4: Convert 0.5%

0.5% = 0.5 ÷ 100 = 0.005

Small percentages become very small decimals

Why This Works

"Percent" literally means "per hundred" (from Latin "per centum"). So 75% means "75 per 100" or 75/100.

The Logic:

• 75% = 75 per 100 = 75/100 = 0.75
• 50% = 50 per 100 = 50/100 = 0.50 = 0.5
• 100% = 100 per 100 = 100/100 = 1
• 200% = 200 per 100 = 200/100 = 2

Dividing by 100 is the same as moving the decimal point two places to the left!
