No, 2/sqrt8 is an irrational number.

Explanation:

2/sqrt8 is an irrational number. The definition of a rational number is a number that is an integer divided by an integer in the form of p/q (i.e. 1, 1/2).

2/sqrt8 is in the form of p/q but sqrt8 is not an integer, it is a rational number.

So then what is an irrational number? An irrational number is basically when the number gives you an ongoing decimal.
2/sqrt8=2.8284....
