What is a Decimal to Fraction?
A decimal is a number written using a decimal point, such as 0.5, 0.25, or 3.75. A fraction represents a part of a whole and is written as a numerator over a denominator, such as 1/2, 1/4, or 15/4.
Converting decimals into fractions makes mathematical calculations easier and provides exact values without rounding errors.
Decimal to Fraction Examples
| Decimal | Fraction |
|---|---|
| 0.5 | 1/2 |
| 0.25 | 1/4 |
| 0.75 | 3/4 |
| 1.5 | 3/2 |
| 2.25 | 9/4 |
| 3.125 | 25/8 |
How to Convert a Decimal to a Fraction
Step 1: Write the Decimal as a Fraction
Place the decimal number over a power of 10.
0.75 = 75/100
Step 2: Simplify the Fraction
Divide both the numerator and denominator by their greatest common divisor (GCD).
75 ÷ 25 = 3
100 ÷ 25 = 4
Therefore, 0.75 = 3/4
Decimal to Fraction Formula
Here, n represents the number of digits after the decimal point. After creating the fraction, simplify it to its lowest terms.
Example Calculation
Convert 0.125 into a fraction:
0.125 = 125/1000
Divide numerator and denominator by 125:
125 ÷ 125 = 1
1000 ÷ 125 = 8
Answer: 1/8
