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.
No, they are not. Recurring decimals are rational.
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)
that is called an irrational number
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...
