No.
rational
If the decimal of a fraction either terminates or ends with a repeating cycle of digit(s) then it is a rational number; otherwise it does not terminate nor does it have a repeating cycle of digit(s) at the end and is irrational. 0.12345 terminates as so it rational If that was repeating, as in 0.123451234512345..., then it is still rational.
1/3. The full answer is irrational (0.3333 repeating) * * * * * The full answer, 0.33... repeating, is rational, not irrational.
No, no repeating decimal is irrational. All repeating decimals can be converted to fractions. They are, however, non-terminating.
it is irrational
Actually, a repeating decimal is not necessarily an irrational number. A repeating decimal is a decimal number that has a repeating pattern of digits after the decimal point. While some repeating decimals can be irrational, such as 0.1010010001..., others can be rational, like 0.3333... which is equal to 1/3. Irrational numbers are numbers that cannot be expressed as a simple fraction, and they have non-repeating, non-terminating decimal representations.
yes
No.
Not necessarily. Remember that the definition of an irrational number is a number that can't be expressed as a simple fraction. 2/3, for example, is rational by that definition even though its decimal form is a repeating decimal. Since irrational numbers cannot be written as fractions, they don't have fraction forms. So basically, numbers with repeating decimals are considered rational. Irrational numbers don't have repeating decimals.
It is an irrational number. Actually it is a rational number. Think 2/3=.6666666, 1/9=.11111111.
