Best Answer

A rational number is one that can be expressed as a ratio of two integers, the second of which is not zero. An irrational number is any real number that is not rational.

Being rational or irrational is not about "predicting the next digit"; the definition of a rational number is that you can write it as a fraction, with integer numerator and denominator.Being rational or irrational is not about "predicting the next digit"; the definition of a rational number is that you can write it as a fraction, with integer numerator and denominator.Being rational or irrational is not about "predicting the next digit"; the definition of a rational number is that you can write it as a fraction, with integer numerator and denominator.Being rational or irrational is not about "predicting the next digit"; the definition of a rational number is that you can write it as a fraction, with integer numerator and denominator.

A rational number is one that can be expressed as a ratio of two whole numbers (like a fraction). An irrational number is a real number that is not rational.

By definition, an irrational number is a number that is not rational, or in other words a number that cannot be expressed as an integer divided by another integer. A number cannot be both "rational" and "not rational."

There is no such thing as a number that is both rational and irrational. By definition, every number is either rational or irrational.

No. Any fraction with integers in the numerator and in the denominator is, by definition, RATIONAL.

A real number that can not be expressed as a rational number.

Rational

Zero is a rational number, and therefore is NOT an irrational number. The definition of a rational number is any number that can be expressed as a fraction where the numerator and demoninator are both integers, and the denominator is non-zero. Irrational numbers are all real numbers that are not rational numbers. Since zero qualifies under the definition of a rational number, (0/3, for example), it therefore cannot be an irrational number.

RATIONAL , because you can convert it to a RATION (FRACTION). Method Let P = 0.272727.... Then 100P = 27.272727.... Subtract 99P = 27 (Note the decimals to infinity subtract to zero. P = 27/99 Cancel down by '9' P = 3/11 ( Which is a RATIO/rational). Since both '3' & '11' are prime numbers this will not cancel down any further. Hence 3/11 = 0.272727....
