a decimal in which a digit or group of digits repeats without end

A decimal is a rational number if it ever ends, or if it repeats the same single digit or set of digits forever.

With repeats: 4×4 = 16; Without repeats: 4×3 = 12.

Without repeats there are 4 × 3 = 12 possible 2 digit numbers. With repeats there are 4 × 4 = 16 possible 2 digit numbers.

The first occurrence of the digit 0 in the digits of pi is at the 32nd decimal place.

a decimal in which a digit or group of digits repeats without end

A repeated decimal is a decimal representation of a number in which, following a finite string of digits, the decimal digits settles into a string which repeats itself again and again - forever. For example, 111.11/77 = 1.44298701298701... The repeating pattern 298701 appears after the first three digits of the decimal representation.

In the decimal expansion of , the digit repeats indefinitely.

A decimal is a rational number if it ever ends, or if it repeats the same single digit or set of digits forever.

With repeats: 4×4 = 16; Without repeats: 4×3 = 12.

When you convert a fraction to a decimal sometimes the decimal repeats forever. For example 1/3 as a decimal = 0.333333333.... (or 0.3 "recurring"). Another example is 1/7=0.142857142857.... (or 0.142857 recurring).

Without repeats there are 4 × 3 = 12 possible 2 digit numbers. With repeats there are 4 × 4 = 16 possible 2 digit numbers.

No, there can be any finite number of repeating digits. For example, 1/9 = 0.101010... where 10 repeats. Division by 7 gives rise to a six-digit string which repeats.

It can be any digit. 1/9 = 0.1111... 2/9 = 0.2222... etc 1.0 = 0.99999.... (odd though that might seem, it is mathematically true.) Or it can be different strings of digits: Division by 7 gives 142857 Division by 13 gives 307692

With repeats: 8^5 = 32768 Without repeats: 8 x 7 x 6 x 5 x 4 = 6720
