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.

1. Convert 3/4 to percent: 75%
2. Convert whole number: 1 × 100% = 100%
3. Add: 100% + 75% = 175%

Method 2: Convert to improper fraction first.

1. 1 3/4 = 7/4
2. 7 ÷ 4 = 1.75
3. 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.
