1/4 as a decimal, a seemingly simple concept, holds a surprising amount of power. This fraction, representing one-quarter of a whole, is commonly used in everyday life, from splitting bills with friends to calculating discounts. Understanding how to convert fractions to decimals unlocks a world of practical applications, simplifying calculations and enhancing our understanding of numerical relationships.
The conversion process itself is straightforward. By dividing the numerator (1) by the denominator (4), we arrive at the decimal equivalent of 1/4, which is 0.25. This simple calculation provides a clear representation of the fraction, making it easier to visualize and use in various contexts.
Understanding Fractions and Decimals: 1/4 As A Decimal
Fractions and decimals are two different ways to represent parts of a whole. A fraction represents a part of a whole as a ratio of two numbers, the numerator and the denominator. A decimal, on the other hand, represents a part of a whole as a number with a decimal point.
The relationship between fractions and decimals is that they both represent the same value, just in different forms. A fraction can be converted to a decimal by dividing the numerator by the denominator.
Examples of Fractions as Decimals
- 1/2 = 0.5
- 3/4 = 0.75
- 1/10 = 0.1
Converting a Fraction to a Decimal
To convert a fraction to a decimal, simply divide the numerator by the denominator.
For example, to convert 1/4 to a decimal, divide 1 by 4.
Converting 1/4 to a Decimal
Process of Dividing 1 by 4
To convert 1/4 to a decimal, we perform long division. Here’s how it works:
- Set up the division problem with 1 as the dividend and 4 as the divisor.
- Since 4 cannot go into 1, we add a decimal point and a zero to the right of 1, making it 1.0.
- Now, 4 goes into 10 two times (4 x 2 = 8). Write 2 above the decimal point in the quotient.
- Subtract 8 from 10, leaving 2.
- Bring down another zero, making it 20.
- 4 goes into 20 five times (4 x 5 = 20). Write 5 next to 2 in the quotient.
- Subtract 20 from 20, leaving 0.
Resulting Decimal Value
Therefore, 1/4 is equal to 0.25.
