Step-by-step explanation:

We have according to the options:

B. $13.5+\sqrt{81} =13.5+9=22.5$

C. $\sqrt{9}+\sqrt{729}=3+27=30$

D. $\sqrt{64}+\sqrt{353}=8+\sqrt{353}$, which is not rational.

E. $\frac{1}{3}+\sqrt{216}=0.3+6\sqrt{6}$, which is not rational.

F. $\frac{3}{5}+2.5=0.6+2.5=3.1$

Hence, the expressions representing rational numbers are A, B, C and F.
