an irrational number is any real number that cannot be expressed as a ratio a/b, where a and bare integers, with b nonzero, and is therefore not a rational number.
Informally, this means that an irrational number cannot be represented as a simple fraction. Irrational Numbers are those real numbers that cannot be represented as terminating or repeating decimals. As a consequence of Cantor's proof that the real numbers are uncountable (and the rationals countable) it follows that almost all real numbers are irrational.[1]

Can an irrational number be a decimal if so give an example?
Irrational numbers are decimal numbers that can't be expressed as fractions. An example is the square root of 2
Give an example of two irrational numbers whose product is not irrational?
(pi) x (1/pi) = 1
Can multiplying two irrational numbers give you an irrational number?
Yes. For example, the square root of 3 (an irrational number) times the square root of 2(an irrational number) gets you the square root of 6(an irrational number)
Define and give example of natural numbers?
Any positive integer not including 0. Also known as "counting numbers." 1,2,3,4,5,6,7,8,9,10,11...
