Definition of Non-terminating Decimal:
While expressing a fraction in the decimal form, when we perform division we get some remainder. If the division process does not end i.e. we do not get the remainder equal to zero; then such decimal is known as non-terminating decimal.
In some cases, a digit or a block of digits repeats itself in the decimal part. Such decimals are called non-terminating Strike Strike GBX GBX GBX BlackWhite BlackWhite BlackWhite Strike repeating decimals or pure recurring decimals. These decimal numbers are represented by putting a bar on the repeated part.
Example of Non-terminating Decimal:(a) 2.666... is a non-terminating repeating decimal and can be expressed as 2. 6.

• In some cases at least one of the digits after the decimal point is not repeated and some digit/digits are repeated, such decimals are called mixed recurring decimals.
