Converting Decimals to Fractions: A Step-by-Step Guide
Converting decimals to fractions can be a daunting task for many students and professionals alike. However, with the right approach and techniques, it can be made easy and straightforward. In this article, we will explore the simple steps to convert the decimal 1.214 to its fraction form.
Understanding the Basics of Decimals and Fractions
Before we dive into the conversion process, it's essential to understand the basics of decimals and fractions. A decimal is a number that represents a fraction of a whole, while a fraction is a way of expressing a part of a whole as a ratio of two numbers. For example, the decimal 0.5 can be written as the fraction 1/2.
Step-by-Step Guide to Converting 1.214 to Fraction Form
Converting 1.214 to fraction form is a simple process that involves a few steps:
Step 1: Write the Decimal as a Fraction
The first step is to write the decimal 1.214 as a fraction. To do this, we can express it as:
1.214 = 1 + 0.214
We can then rewrite the decimal part (0.214) as a fraction:
0.214 = 214/1000
Step 2: Simplify the Fraction
Now that we have expressed the decimal part as a fraction, we can simplify it by dividing both the numerator and the denominator by 2:
214 ÷ 2 = 107 1000 ÷ 2 = 500
Therefore, the simplified fraction is:
0.214 = 107/500
Step 3: Combine the Whole Number and Fraction
Now that we have simplified the fraction, we can combine it with the whole number part:
1.214 = 1 + 107/500
We can then rewrite this expression as a single fraction:
1.214 = (1 x 500 + 107) / 500 = 607/500
Step 4: Reduce the Fraction to its Simplest Form
Finally, we can reduce the fraction to its simplest form by dividing both the numerator and the denominator by their greatest common divisor (GCD). In this case, the GCD of 607 and 500 is 1, so the fraction remains the same:
1.214 = 607/500
