Answer:

Option A.

Step-by-step explanation:

If a fraction p/q is in the simplified form, then it can be represented by terminating or non-terminating decimal.

If the denominator is 2, 5 or multiple of either 2 or 5, or both, then the fraction can represented by terminating decimal. Otherwise, the fraction can represented by non-terminating decimal.

Only in option A, the denominator is 5. So, only 8/5 an be represented by a terminating decimal.

frac{8}{5}=1.6

frac{8}{3}=2.666...

frac{1}{11}=0.0909...

frac{4}{9}=0.444...

Only 8/5 is terminating.

Therefore, the correct option is A.
