What is 66.6 recurring?

Answer 1

Two thirds of 100. If you divide 100 by 3 you get 33.333333 continued to an infinite amount of places. x2 gives 66.666666 to an infinite amount of places.

Recurring means it just keeps going

Answer 2

66.6 recurring, often denoted as 66.6 with a bar over the six, represents a repeating decimal where the digit 6 repeats infinitely. This can be expressed as 66.666..., with the decimal point followed by an infinite string of 6s. In fraction form, this recurring decimal is equivalent to 2/3, as the fraction 2 divided by 3 results in 0.666..., which is the same as 66.6 recurring when multiplied by 10.
