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.
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.
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.
A rational number can be expressed as a fraction whereas an irrational number can't be expressed as a fraction.
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.
4.6 is rational.
10.01 is a rational number
Rational
is 34.54 and irrational or rational. 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....

If x is rational the it is rational. If x is irrational then it is irrational.

No. A rational plus an irrational is always an irrational.
