D.) 32/9
3 answers
We can see that $3.5=3\frac{1}{2}=\frac{6}{2}=\boxed{\textbf{(B)}\ 24/9}$.
x / 9 = 3.5
x = 9 * 3.5 = 31.5
so
31.5 / 9 = 3.5
unfortunately 31.5 is not one of your choices
x = 9 * 3.5 = 31.5
so
31.5 / 9 = 3.5
unfortunately 31.5 is not one of your choices
Actually, since $x$ is a rational number, it can only be one of the given answer choices. In this case, we have $x = \frac{35}{9}$ (choice C) which equals $3.888\dots$. It is not possible for $x$ to equal $31.5$ in this equation.
