Pure Recurring Decimal – Definition
A Decimal in which all the digits in the decimal part are repeated is called a Pure Recurring Decimal.
For Example: When 5/3 is divided the quotient is 1.6666…. and all the digits in the decimal part repeat continuously it is called a Pure Recurring Decimal.
How to Identify a Pure Recurring Decimal?
Follow the simple guidelines on how to identify a pure recurring decimal. They are in the following fashion
- Firstly, divide the numerator with the denominator from the given fraction.
- After dividing if you get to see all the digits in the decimal part repeat infinitely then it is called a pure recurring decimal.
For a better understanding of the concept of Pure Recurring Decimals check out few worked-out examples provided in the later sections.
Pure Recurring Decimal Examples
1. Is \(\frac { 5 }{ 3 } \) a Pure Recurring Decimal?
Solution:
Simply divide the numerator 5 with denominator 3. Check for if all the digits in the decimal part repeat or not after performing the division process. Simply place a bar on the repeating digits itself.
\(\frac { 5 }{ 3 } \) = 1.66666……
Thus, \(\frac { 5 }{ 3 } \) expressed in decimal form is 1.6666…. or 1.\(\overline{6}\)
1.6666…. is called a Pure Recurring Decimal as it has all the digits after the decimal part repeating.
2. Is \(\frac { 7 }{ 3 } \) a Pure Recurring Decimal?
Solution:
Simply divide the numerator 7 with denominator 3. Check for if all the digits in the decimal part repeat or not after performing the division process. Simply place a bar on the repeating digits itself.
\(\frac { 7 }{ 3 } \) = 2.333333……
Thus, \(\frac { 7 }{ 3 } \) expressed in decimal form is 2.3333…. or 2.\(\overline{3}\)
2.3333…. is called a Pure Recurring Decimal as it has all the digits after the decimal part repeating.
