Which Decimal Is Equivalent To 2/27

Finding the Decimal Equivalent of 2/27: A Step-by-Step Guide

Have you ever struggled to simplify fractions into their decimal counterparts? If so, you’re not alone. Determining the decimal equivalent of a fraction can be a daunting task, but it doesn’t have to be.

One common fraction that many students stumble upon is 2/27. If you’ve ever encountered this fraction and wondered how to convert it into a decimal, you’ve come to the right place. Let’s dive into the process and make this fraction conversion a breeze.

Converting 2/27 to a Decimal

To convert the fraction 2/27 into a decimal, we simply need to divide the numerator (2) by the denominator (27). Here’s a step-by-step guide:

2 / 27 = 0.074074074…

The result, 0.074074074…, is an infinite decimal. This means that the decimal representation of 2/27 continues forever, with the digits 740 repeating.

Since this representation is infinite, we can round it to a specific number of decimal places depending on the desired level of precision. For example, we can round the decimal to:

  • 2 decimal places: 0.07
  • 4 decimal places: 0.0741
  • 6 decimal places: 0.074074

Decimal Equivalent of 2/27

Introduction

In mathematics, decimals provide a convenient representation of fractions. They allow us to express rational numbers in a user-friendly format. This article explores the decimal equivalent of the fraction 2/27.

Dividing the Numerator by the Denominator

The first step in finding the decimal equivalent is to divide the numerator (2) by the denominator (27). The division process is as follows:

27 | 2
    -----
    27 | 0.074
       -----
       27 | 0.007
           -----
           27 | 0.000259...

Repeating Decimal

As you can see from the division process, the decimal does not terminate and instead continues indefinitely. This indicates that the fraction 2/27 is a repeating decimal.

Terminating the Decimal

To express the decimal in a concise form, we can round it to a desired number of decimal places. For instance, rounding the decimal to the nearest hundredth would give us:

2/27 = 0.07

Scientific Notation

An alternative way to represent the decimal equivalent is using scientific notation. This notation is useful for expressing very large or very small numbers. In this case, we can write:

2/27 = 7.407407 x 10^-2

Percentage

The decimal equivalent can also be expressed as a percentage. To do this, multiply the decimal by 100. This gives us:

2/27 = 0.07 x 100 = 7%

Approximations

In certain situations, it may be sufficient to use an approximation of the decimal. One common approximation for 2/27 is:

2/27 ≈ 0.074
