no its not an irrational no.
because it is non-terminating &repeating&
can be represented as a fraction [a no. is irrational when it is non-terminating and non-repeating and which can not be represented as afraction ]
Ans: In mathematics, an irrational number is any real number which cannot be expressed as a fraction a/b, where a and b are integers, with b non-zero
Hence 7/6 is not a irrational number
as here
both a and b are integers and b = 6 not zero.
