How to Convert a Fraction to a Decimal

A fraction represents a division problem. The line separating the top number (numerator) and the bottom number (denominator) is simply a division symbol. Therefore, converting any fraction into its decimal format is as simple as dividing the numerator by the denominator.

1

Divide the Numerator by the Denominator Perform standard division of the top number by the bottom number. For example, to convert the fraction ¾:
3 ÷ 4 = 0.75.

2

For Mixed Numbers, Add the Whole Number If your fraction is a mixed number (like 2 ½), keep the whole number (2) as-is. Divide the fractional part (1 ÷ 2 = 0.5) and add them together:
2 + 0.5 = 2.5.

Decimal = Numerator ÷ Denominator Example: ⅜ → 3 ÷ 8 = 0.375

📊 Excel Formula: Convert Text Fractions to Decimals

If you type a fraction (like =3/4) into an Excel cell, Excel automatically converts it to 0.75. However, if your fraction is stored as a text string (like "3/4" inside cell A1), you can convert it to decimal using this formula:

=LEFT(A1, FIND("/", A1) - 1) / MID(A1, FIND("/", A1) + 1, LEN(A1))

How it works: The formula isolates the text to the left of the slash as the numerator, and divides it by the text to the right of the slash (the denominator).

The Secret Link to Payroll & Time Cards

Did you know that calculating employee pay or logging time cards is fundamentally a fraction-to-decimal conversion? Under standard labor guidelines, an hour contains 60 minutes. Therefore, any minute value logged represents a fraction of an hour [2].

15 minutes = ⅕ of an hour = 15 ÷ 60 = 0.25 decimal hours [2]
30 minutes = ½ of an hour = 30 ÷ 60 = 0.50 decimal hours [2]
45 minutes = ¾ of an hour = 45 ÷ 60 = 0.75 decimal hours [2]

Using our main Hours to Decimal Calculator handles these exact conversions automatically for your workplace timesheets.
