### Instruction: Simplify $3\cdot\frac{11}{4}\cdot \frac{16}{-55}$.### Response: Let's start by simplifying $3\cdot\frac{11}{4}$.
Ok. $3\cdot\frac{11}{4} = \frac{3\cdot11}{4}$.
Right. And $3\cdot11=33$.
That means $3\cdot\frac{11}{4} = \frac{33}{4}$.
Now let's multiply $\frac{33}{4}\cdot\frac{16}{-55}$.
That's $\frac{33\cdot16}{4\cdot-55}$.
And 33*16 is 528.
And 4*-55 is -220.
So $\frac{33\cdot16}{4\cdot-55}=\frac{528}{-220}$.
And that's -2.4.
