What is a Fraction?
A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.
Every fraction consists of two parts: the numerator and the denominator. The numerator represents the number of equal parts, while the denominator indicates how many of those parts make up a whole.
Converting Decimals to Fractions
Converting decimals to fractions is a fundamental skill in mathematics. It involves expressing a decimal number as a fraction in its simplest form. Let's explore the process in more detail.
Step-by-Step Guide
Here's how you can convert a decimal like .625 into a fraction:
- Step 1: Write down the decimal as a fraction with 1 as the denominator. For .625, it becomes 0.625/1.
- Step 2: Eliminate the decimal by multiplying both the numerator and denominator by 10 for every digit after the decimal point. Since .625 has three digits after the decimal, multiply by 1000.
- Step 3: Simplify the fraction to its lowest terms by dividing both the numerator and denominator by their greatest common divisor (GCD).
Understanding .625 as a Fraction
.625 is a decimal that can be easily converted into a fraction. As we've seen in the previous section, the process involves writing it as a fraction and simplifying it. When converted, .625 becomes 5/8.
This fraction represents five parts out of eight equal parts of a whole. It's a simple yet powerful way of expressing the same value in a different format.
