How to Convert a Fraction to Percent
Converting a fraction to a percentage is a simple two-step process: divide, then multiply by 100.
Step One: Convert to a Decimal
Divide the numerator by the denominator to get a decimal value.
Example: Convert 3/4 to a percentage.
- 3 ÷ 4 = 0.75
The fraction does not need to be in simplest form — 6/8 gives the same result (6 ÷ 8 = 0.75).
Step Two: Multiply by 100
Multiply the decimal by 100 (or move the decimal point two places right) and add a percent sign.
- 0.75 × 100 = 75%
So 3/4 as a percent is 75%.
How to Convert a Mixed Number to Percent
For a mixed number like 1 3/4, you have two approaches:
Method 1: Convert fraction part, add whole part.
- Convert 3/4 to percent: 75%
- Convert whole number: 1 × 100% = 100%
- Add: 100% + 75% = 175%
Method 2: Convert to improper fraction first.
- 1 3/4 = 7/4
- 7 ÷ 4 = 1.75
- 1.75 × 100 = 175%

Frequently Asked Questions
What is the formula to convert a fraction to a percent?
The formula is: Percent = (numerator ÷ denominator) × 100. Divide the top by the bottom to get a decimal, then multiply by 100 to get the percentage.
Can a fraction be more than 100%?
Yes — any improper fraction (numerator ≥ denominator) converts to 100% or more. For example, 5/4 = 125%, and 2 1/2 = 250%. This simply means the fraction represents more than one whole.
What about repeating decimals like 1/3?
1/3 = 0.3333… = 33.33…% (repeating). The calculator shows this rounded to a reasonable number of decimal places. The exact value is 33⅓%.
Is 1/2 always 50%?
Yes — 1/2 = 0.5 = 50%, always. Any equivalent fraction like 2/4, 3/6, 50/100 also equals 50%.
How do I convert a percent back to a fraction?
Divide the percent by 100 to get a decimal, then convert the decimal to a fraction. For example, 75% = 0.75 = 3/4.
Where:
- n = Numerator of the fraction
- d = Denominator of the fraction
