A real number is an irrational number if it cannot be expressed as a fraction a/b, where a and b are integers. Most real numbers are irrational. The most well known Irrational Numbers are π and √2. The inverse condition are called the rational numbers.

If x is a rational number and y is an irrational number what can you say about x plus y?
It is irrational.
Is 0.83 an irrational number?
I would say no, it is rational. A number is only irrational if it repeats with no specific pattern.
Are fractions irrational numbers?
NO. The word irrational means "cannot be expressed as a ratio". A fraction IS a ratio. For instance: in the ratio 1:3 , the total number of shares is 4(=1+3). The share 1 is 1/4 of the total. Since a fraction is a ratio, it is WRONG to say it is irrational, which would mean it is not a fraction (or ratio). However, it is also good to take note that even an irrational number is a real number.
Which irrational number is closest to 6?
The irrational number closest to 6 is the square root of 36, which equals 6. This is because the square root of 36 is a rational number that is the closest approximation to 6 among irrational numbers. The square root of 36 is equal to 6, making it the irrational number closest to 6.
Why does a rational number plus an irrational number equal an irrational number?
from another wikianswers page: say that 'a' is rational, and that 'b' is irrational. assume that a + b equals a rational number, called c. so a + b = c subtract a from both sides. you get b = c - a. but c - a is a rational number subtracted from a rational number, which should equal another rational number. However, b is an irrational number in our equation, so our assumption that a + b equals a rational number must be wrong.
