Converting fractions to decimals is a fundamental math concept that helps us understand and work with numerical values in different forms. Let's dive into the world of fractions and decimals to explore how to convert 1/12 into a decimal value.
Understanding Fractions and Decimals
Fractions represent a part of a whole as a ratio of two numbers. The top number, known as the numerator, indicates how many equal parts we have, while the bottom number, the denominator, tells us how many parts the whole is divided into. Decimals, on the other hand, express a value as a fraction of 10, 100, 1000, etc.
Converting 1/12 to a Decimal
To convert the fraction 1/12 to a decimal, we need to divide the numerator (1) by the denominator (12).
Performing the division gives us:
1 ÷ 12 = 0.083333...
The repeating sequence of 3's indicates that the decimal representation of 1/12 is a recurring decimal.
Recurring Decimals
Recurring decimals, also known as repeating decimals, have a block of digits that repeats indefinitely. In the case of 1/12, the decimal representation is 0.083333..., where the sequence of 3's repeats without end.
Rounding Recurring Decimals
Since recurring decimals cannot be expressed exactly as a finite decimal, we often round them to a certain number of decimal places. For example, rounding 1/12 to four decimal places gives us:
0.0833
Rounding can be useful for approximations, but it's essential to understand that the original fraction 1/12 has an infinite number of decimal places.
Conclusion and Next Steps

What is the decimal representation of 1/12?
+The decimal representation of 1/12 is 0.083333...
Why do recurring decimals have an infinite number of decimal places?
+Recurring decimals have an infinite number of decimal places because they represent a fraction with a denominator that is not a power of 10.
How do I round a recurring decimal to a certain number of decimal places?
+To round a recurring decimal to a certain number of decimal places, simply truncate the decimal expansion at the desired place and round up or down as needed.
