Is 5.75 repeating a rational number or irrational?
It is a rational number.
Is 1.6666 a irrational 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.
How do you know if a decimal is rational or irrational?
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!
Is .345 repeating an irrational or rational number?
Any repeating decimal digits (this includes repetition after a certain point, e.g. 2.4510101010...) is a rational number.
Is 5.39 repeating rational or irrational?
It is a rational number because it can also be expressed as a fraction

Is 3.40764076407640764076 rational or irrational?
3.407640764076407640764076(not repeating) is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction. ---- 3.407640764076407640764076 = 3407640764076407640764076/1000000000000000000000000 Which is of the form of one_integer/another_integer so it a rational number. 3.4076... (where the 4076 repeats forever): 3.4076... = 34076/9999 = 34073/9999 Again of the form of one_integer/another_integer so it a rational number. Either way, 3.4076...4076 is a rational number. Decimal numbers that terminate, or go on forever with repeating a sequence of digits are rational. Decimal numbers that go on forever without repeating a sequence of digits are irrational, eg √2.
Is 0.23 repeating a rational irrational or a whole number or an integer?
