Answer:
No; irrational
Explanation:
-5 div'd by -7 would be the same as 5/7.
A rational number is a number that can be either repeats (decimal), is a whole number, or is shown as a fraction/sq. rt.
Div'g 5 by 7 would result in a long, non-repeating decimal: 0.71428571428. Since this decimal doesn't repeat it is an irrational number. The answer is no.
