What is rational and irrational behavior?

Answer 1

irrational numbers are real numbers , which are not rational.

rational numbers are numbers which can be expressed as fractions a/b where b is not equal to 0 , since b may be equal to 1 , every integer is a rational number.

Answer 2

Rational in the "rational number" sense means "capable of being expressed as a ratio" ... specifically, as a ratio of whole numbers. If you can write it as i/j where I and J are both integers (and J is not zero), then it's a rational number. Any number which can be written exactly as a decimal number that either terminates or repeats (for example, 0.25 (terminates) or 0.3333... (repeats)) is a rational number (those examples are 1/4 and 1/3 respectively).

An irrational number is a number that cannot be written that way. Irrational Numbers have infinite, nonrepeating decimal expansions.

Answer 3

Something that is rational is usual - it happens often and follows normal rules. An irrational number, for example, is Pi. It is irrational since you cannot define its complete true value.

Answer 4

A rational number can be expressed as a fraction whereas an irrational number can't be expressed as a fraction.

Answer 5

A rational number is one that can be written as a whole number

divided by another whole number.

An irrational number is one that can't.
