2 min read 29-09-2024

Converting decimals to fractions can often seem daunting, especially when dealing with repeating decimals like 0.16666666666. This article will walk you through the process of converting this decimal into a fraction, while providing additional insights and practical examples to enhance your understanding.

Understanding the Decimal

The number 0.16666666666 is a decimal representation of a number that has a repeating decimal part. Specifically, the digit "6" repeats infinitely. This repeating decimal can be expressed more concisely as (0.1\overline{6}), indicating that the "6" will continue indefinitely.

Step-by-Step Conversion

To convert the repeating decimal (0.1\overline{6}) to a fraction, we can follow these systematic steps:

Step 1: Set Up the Equation

Let (x) equal the repeating decimal:

[ x = 0.16666666666\ldots ]

Step 2: Eliminate the Repeating Part

To eliminate the repeating part, we can multiply the entire equation by 10 (since there is one non-repeating digit before the repeating part):

[ 10x = 1.66666666666\ldots ]

Step 3: Create a Second Equation

Now, we will create another equation with the original (x):

[ x = 0.16666666666\ldots ]

Step 4: Subtract the Two Equations

Now, subtract the first equation from the second:

[ 10x - x = 1.66666666666\ldots - 0.16666666666\ldots ]

This simplifies to:

[ 9x = 1.5 ]

Step 5: Solve for (x)

Now, isolate (x) by dividing both sides by 9:

[ x = \frac{1.5}{9} ]

To simplify this fraction, convert 1.5 to a fraction:

[ x = \frac{15}{90} ]

Reducing this fraction gives:

[ x = \frac{1}{6} ]

Conclusion: The Fraction Representation

Thus, the decimal (0.16666666666) can be expressed as the fraction (\frac{1}{6}).

Why Convert Decimals to Fractions?

Understanding how to convert decimals to fractions is a valuable skill in mathematics, as it allows for easier calculations and clearer representations of ratios. Fractions often provide more insight into the relationships between numbers, especially in fields like engineering, physics, and statistics.

Practical Example of Usage

In practical terms, if you were to divide a pizza into 6 equal slices and eat 1 slice, you would have consumed (\frac{1}{6}) of the pizza. This fraction provides a more intuitive understanding of how much of the whole pizza has been eaten compared to the decimal representation.

Conclusion

By following the steps outlined above, we have successfully converted the repeating decimal (0.16666666666) into its fractional form, (\frac{1}{6}). This process not only highlights the method of conversion but also emphasizes the practical implications of understanding fractions in everyday life.

For further exploration of decimal and fractional conversions, consider practicing with other repeating decimals, such as (0.3333\overline{3}), which converts to (\frac{1}{3}), or (0.75), which simplifies directly to (\frac{3}{4}).
