Understanding Decimal to Fraction Conversion
To truly grasp how decimals relate to fractions, it’s important to understand the basics:
What is a Decimal?
A decimal is a way of representing numbers that aren’t whole. It uses a decimal point to separate the whole number part from the fractional part. For instance, in 3.14, 3 is the whole number, and .14 is the fractional part.
What is a Fraction?
A fraction represents a part of a whole. It consists of two parts:
- Numerator: The number above the line
- Denominator: The number below the line
For example, in 3/4, 3 is the numerator, and 4 is the denominator.
How the Conversion Works
The process of converting a decimal to a fraction involves these steps:
- Write the decimal as a fraction over 1.
- Multiply both top and bottom by 10 for each decimal place.
- Simplify the fraction if possible.
Let’s convert 0.75 to a fraction:
- 0.75 = 0.75/1
- Multiply by 100/100 (because there are two decimal places) 0.75/1 * 100/100 = 75/100
- Simplify: 75/100 = 3/4
Our calculator performs these steps instantly, saving you time and effort.
