Is -140/79 a rational or irrational?

Question

So I have this problem because -140/79 is 1.772151.......(repeated decimal), so that should be a irrational. But when I tried to enter this answer, it says that -140/79 is rational.

Is there an explanation for this because my system does not explain to me why and I want to know why this is a rational instead of an irrational.

Thank you!

Answer 1

A ratio of two integers is a rational number. Both -140 and 79 are integers.
