Yes. Rational numbers are numbers or decimals that repeat or terminate. Irrational numbers do not. For example π is an irrational number.

Any irrational number can be approximated by decimals. You can never write it exactly, since there are an infinite number of decimals, and these don't repeat.

That can refer to one of two types of decimals: terminatingand irrational.Terminating decimals don't repeat because they stop, whereas irrational decimals simply never repeat a distinct pattern of digits.

There are irrational numbers (like PI and e) that have infinitely many decimals which do not repeat and rational numbers (the quotient of two integers) which do eventually repeat.

Decimals that terminate or repeat in some fashion are rational, while decimals that expand forever are irrational.

only decimals that never end and never repeat are irrational. a decimal is rational if it can be written as a fration or ratio of two numbers. for example: .3434343434343434... 100x=34.34343434... -x 99x=34 34/99

Irrational numbers are real numbers which cannot be expressed as fractions. In other words, decimals that never repeat. Examples: sqrt(2) -pi 4*sqrt(3)

Irrational numbers.

No, -3 is a rational number. All fractions are rational along with all decimals that terminate or repeat. (this applies to both positive and negative numbers.)

Pi is an irrational number. That means that it never stops and will never repeat itself. The first 85 decimals without rounding are 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280...

No, no repeating decimal is irrational. All repeating decimals can be converted to fractions. They are, however, non-terminating.

No. If they are recurring, then they are rational.

No integers are irrational numbers. An integer is a whole number, positive or negative. This means they have no decimals or fractions. An irrational number, however, is a number with fractions or decimals. Therefor, there are no integers that are irrational numbers.

Infinitely many. pi is not just an irrational number but a transcendental number. All irrational numbers have infinite decimals that do not go into a recurring pattern.

Because decimal numbers that can't be expressed as fractions are irrational numbers whereas all rational numbers can be expressed as decimals or fractions.
