It is a repeating decimal.
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.
It depends on what you mean by three digit decimal. If you mean three digits after the decimal, then it's 0.999. However, if you mean three digits in the number, then it's 0.99.
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.

The first occurrence of the digit 0 in the digits of pi is at the 32nd decimal place.
Oh, dude, the period of the underlined digits is just the number of digits in a repeating decimal pattern. It's like when your friend keeps telling the same joke over and over again. So, if you see 0.333... the period of the underlined digits is 1 because it just keeps repeating that "3" forever. It's like a never-ending story, but with numbers.
