Answer:
3/9
Explanation:
A repeating decimal is a decimal in which the last number is the same forever. (Ex. .83333333333333333)
So...
2/5 = .4 Not Repeating
-7 = -7 Just a regular integer so nothing can actually repeat
3/9 = .33333 Yes. the 3 is repeating.
11/12 = 0.916666667 Repeated BUT it ends in 7, it doesn't keep continuing.
Hope this helped :)
