$3 s$

#### Explanation:

You can simplify both the numeric and literal part. Remember that a fraction whose numerator and denominator consist only of multiplication can be arranged as you want. So for example, the following writings are equivalent:

$\setminus \frac{a b c d}{e f g} = \setminus \frac{a b}{e} \setminus \frac{c d}{f g} = \setminus \frac{a}{c} \setminus \frac{b}{f} \setminus \frac{c d}{g} = \ldots$

Let's rewrite our fraction as

$\setminus \frac{12}{4} \setminus \frac{t}{t} s$

As for the first fraction, it is a simple division between numbers, so we know that $12 \setminus \div 4 = 3$

as for the second fraction, its numerator and denominator are the same, so it equals $1$.

So, evertything simplifies to $3 s$
