Understanding 1.4 as a Decimal: A Comprehensive Guide for Quick Conversions

Introduction

Decimals are a common way to express fractions in mathematical operations and everyday life. Understanding how to convert fractions to decimals is crucial for accurate calculations and data interpretation. In this article, we will delve into the conversion of 1 4 as a decimal, exploring its practical applications, common mistakes to avoid, and helpful tips and tricks.

Converting 1 4 to a Decimal

To convert the mixed fraction 1 4 to a decimal, we follow these steps:

1. Separate Whole Number and Fraction: We start by separating the whole number (1) from the fraction (1/4).

   

2. Create an Improper Fraction: We convert the mixed fraction to an improper fraction by multiplying the whole number by the denominator of the fraction and adding the numerator. In this case:

1 × 4 + 1 = 5

3. Write as Division Problem: We create a division problem where the numerator is the improper fraction and the denominator is the denominator of the original fraction:

5 ÷ 4

4. Perform Long Division: We perform long division to find the decimal equivalent. The steps are:

a. Divide 5 by 4: The result is 1 with a remainder of 1.

b. Bring down the 0 as a decimal point: 1.0

c. Divide 10 by 4: The result is 2 with a remainder of 2.

d. Bring down another 0: 1.20

e. Divide 20 by 4: The result is 5 with no remainder.

Final Answer: The decimal equivalent of 1 4 is 1.25.
