Why This Works

A decimal is already a fraction with denominator 100 (or power of 10). Multiplying by 100 converts it to "per hundred" form (percentage).

The Logic:

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

Multiplying by 100 is the same as moving the decimal point two places to the right!

Frequently Asked Questions

How do I convert decimal to percentage?

Simply multiply the decimal by 100. Example: 0.45 × 100 = 45%. Or move the decimal point two places right.

Can decimals be greater than 1?

Yes! 1.5 = 150%, 2 = 200%, 3.5 = 350%. Any decimal can be converted to percentage.

What about negative decimals?

They work the same way! -0.25 = -25%. Used for losses or decreases.

Why do we use percentages instead of decimals?

Percentages are easier to understand and compare. 75% is clearer than 0.75 for most people.

Is 1 the same as 100%?

Yes! 1 = 100% = 1/1 = "the whole thing". They're just different ways to express the same value.
