Let’s convert all terms to the same unit. Since $$1$$ minute equals $$60$$ seconds, we have

$$
720\text{ sec} = \frac{720}{60}=12\text{ min}.
$$

Now the ratio becomes

$$
12\,\text{min} : 6\,\text{min} : 18\,\text{min}.
$$

Next, divide each term by the greatest common divisor, which is $$6$$:

$$
\frac{12}{6} : \frac{6}{6} : \frac{18}{6} = 2 : 1 : 3.
$$

Thus, the simplified ratio is

$$
2:1:3.
$$
The simplified ratio is $$2:1:3$$.
