Converting fractions to decimals is a fundamental math skill with applications across numerous fields, from baking and carpentry to finance and engineering. This printable fraction to decimal conversion chart provides a quick reference guide for common fractions, and also explains the process so you can confidently convert any fraction yourself.
Why Use a Fraction to Decimal Conversion Chart?
A chart offers a convenient and readily available resource for frequently used fractions. This is particularly useful for students, professionals, or anyone who regularly needs to work with fractions and their decimal equivalents. It saves time and ensures accuracy, eliminating the need to perform the calculation each time.
How to Use This Chart (and Create Your Own):
The chart below provides a starting point. You can print it, enlarge it, or use it as a template to create your own more extensive version. To make your own chart, simply perform the division: divide the numerator (top number) by the denominator (bottom number). Remember, a fraction represents a division problem!
Example: To convert 1/4 to a decimal, divide 1 by 4 (1 ÷ 4 = 0.25).
Common Fraction to Decimal Conversions
| Fraction | Decimal | Fraction | Decimal |
|---|---|---|---|
| 1/2 | 0.5 | 1/8 | 0.125 |
| 1/4 | 0.25 | 3/8 | 0.375 |
| 3/4 | 0.75 | 5/8 | 0.625 |
| 1/3 | 0.333... (repeating) | 7/8 | 0.875 |
| 2/3 | 0.666... (repeating) | 1/5 | 0.2 |
| 1/6 | 0.166... (repeating) | 2/5 | 0.4 |
| 5/6 | 0.833... (repeating) | 3/5 | 0.6 |
| 1/10 | 0.1 | 4/5 | 0.8 |
| 1/12 | 0.08333... (repeating) | 1/16 | 0.0625 |
Understanding Repeating Decimals
Notice some fractions, like 1/3, result in repeating decimals (0.333...). These are denoted with an ellipsis (...) or a bar over the repeating digit(s). It's important to understand that these decimals are approximations, as the repeating pattern continues infinitely. In practical applications, you'll often round these decimals to a suitable number of decimal places.
Converting Fractions to Decimals: A Step-by-Step Guide
-
Divide the Numerator by the Denominator: This is the core of the conversion process. Use long division, a calculator, or any method you're comfortable with.
-
Handle Remainders: If the division results in a remainder, you'll either get a terminating decimal (like 1/4 = 0.25) or a repeating decimal (like 1/3 = 0.333...).
-
Rounding (Optional): For repeating decimals, you might need to round to a specific number of decimal places depending on the required level of precision.
Frequently Asked Questions (FAQ)
How do I convert a mixed number to a decimal?
