Unraveling the Mystery: Understanding One Eighth as a Decimal

Introduction

Decimal notations, ubiquitous in everyday life, provide a convenient representation of fractions. Understanding decimal equivalents of simple fractions, such as one eighth, is crucial for various mathematical operations and real-world applications. This guide delves into the concept of one eighth as a decimal, its significance, and practical implications.

What is One Eighth as a Decimal?

One eighth is a fraction that represents a value less than one. It can be expressed in decimal form by dividing the numerator (1) by the denominator (8):

1/8 = 1 ÷ 8 = 0.125

Therefore, one eighth as a decimal is 0.125.

Transition: Understanding the Magnitude of 0.125

0.125 is a decimal number that lies between 0 and 1. It can be visualized as a point on the number line, 0.125 units to the right of 0:

0 

In percentage terms, 0.125 represents 12.5% of a whole. This means that one eighth is equivalent to 12.5% of any quantity it is measuring.
