I need help plz!!
8.57396817...•5/8 is rational or irrational?

Answer 1

Irrational

Explanation:

Any non-zero rational number multiplied by an irrational number will be irrational. We can rewrite this as (8.57... * 5) / 8, but we have no idea how to make 8.57... * 5 rational, or expressed as the quotient of two integers.
