Question

How do you simplify `(12st)/(4t)`?

Answer 1

`3s`

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:

`\frac{abcd}{efg} = \frac{ab}{e}\frac{cd}{fg} = \frac{a}{c}\frac{b}{f} \frac{cd}{g}=...`

Let's rewrite our fraction as

`\frac{12}{4} \frac{t}{t} s`

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

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

So, evertything simplifies to `3s`
