It is a rational number.
Written terminating as it does, it is a rational number. If that is the first bit with the 6 repeating forever (1.666...), then it is still a rational number. Irrational numbers as those numbers in decimal format that neither terminate nor end with a repeating sequence of digits.
A decimal is rational if it:either ends and doesn't go on forever; ORit is a repeating decimal.A decimal is irrational if it goes on forever and ever and never stops without repeating.The number: 5.77777777 is rational because it goes on forever, REPEATING the same number (the digit 7).It can also repeat a group of numbers, like the number: 8.789789789789789789See how the "789" is REPEATING over and over again and never stops? That is a rational decimal!
Any repeating decimal digits (this includes repetition after a certain point, e.g. 2.4510101010...) is a rational number.
It is a rational number because it can also be expressed as a fraction
