Table of Contents :
Converting fractions into decimals can often be a daunting task for many learners, but with a little guidance, it becomes easier than it seems. In this article, we’ll explore how to convert the fraction 1/40 into a decimal and understand the process in a simple and straightforward manner. Let's dive in!
Understanding Fractions and Decimals
Before we start the conversion, it's crucial to understand what fractions and decimals represent.
What is a Fraction?
A fraction consists of two parts:
- The numerator (the top part), which represents how many parts we have.
- The denominator (the bottom part), which tells us how many equal parts make up a whole.
For example, in the fraction 1/40:
- 1 is the numerator
- 40 is the denominator
This means we are looking at one part out of forty equal parts.
What is a Decimal?
A decimal is another way to represent a fraction, where the numerator is divided by the denominator. Decimals use a base-10 system, which is the most common system for representing numbers in mathematics.
Converting 1/40 into Decimal
The process of converting the fraction 1/40 into a decimal involves simple division:
Step-by-Step Conversion
- Set up the division: Divide the numerator (1) by the denominator (40).
- Perform the division:
- When you divide 1 by 40, you will get 0.025.
Calculation Breakdown
To better understand, let’s go through the calculation:
-
Divide 1 by 40:
- You can do this by moving the decimal point to the right in the numerator until you have a whole number or a manageable decimal.
- 1.000 ÷ 40 = 0.025.
-
Confirm the result:
- Multiply back to check your work: 0.025 × 40 = 1.
Thus, the conversion of 1/40 as a decimal is 0.025.
