Answer:
C. 8/9
Explanation:
Well .8 repeating is not 8/10.
Though many would choose that.
If you do 8 ÷ 10 you get .8 not .8 repeating meaning 8/10 is not correct.
To get .8 repeating we would divide 8 by 9.
Because all natural numbers below 9 can be divided by 9 to create a .repeating itself.
For example 8 ÷ 9 = .8 repeating,
4÷9 = .4 repeating.
Thus,
C. is the correct answer.
Hope this helps :)
