because it can be written in the form p/q, where p and q are both integers.

Irrational numbers cannot be represented as a fraction or ratio & they have no square roots.Here 1/3 is represented in the form of fraction.where p & q are two integers. Eg for an irrational number is 2.
1/3=.333333333
It is repeating decimals.So 1/3 is a rational number.

A rational number is a number that can be written as a fraction
0.33333... = 1/3, 4 = 4/1, 22/7(this is not pi ), 3.14 =157/50(this is not pi either)
Any number that is repeating in the decimal can be expressed as a fraction by using the repeating numbers as the numerator. The denominator is a series of 9's(number of 9's is how many numbers in the repeating series)
For example 0.3333.. = 3/9 =1/3
0.4444 = 4/9
0.121212... =12/99 =4/33
0.153153153... = 153/999 =17/111

Seems quite a sensible number really, but I suppose he can be a bit random at times. I would not describe him as irrational though as he can be described by a ratio 1 to 3.

An irrational number cannot be expressed as a ratio. 1/3 is a ratio, and so is a rational number.

Any no. that can be represented in the form p/q (p,q are integers prime to each other, q not equal to zero) is called a rational no. Surely 1/3 falls in this category, so it is not an irrational no.!

An irrational number is one that can not be represented by a fraction. The square root of 2, or pi, for example

1/3 is not an irrational number because it is a rational number...
rational numbers are those terminating and repeating decimals...
irrational numbers are those non-terminating and non-repeating decimals...
1/3 when it is solved by dividing 1 by 3
it will give you an answer of 0.333333333333333
which is a repeating decimal so it is not an irrational number.
