Question

Number 18 please help

Answer 1

Answer:

D.

Step-by-step explanation:

First, multiply straight across and put everything together:

$\frac{3a}{b}\cdot \frac{b^2}{12c}=\frac{3ab^2}{12cb}$

Notice we can simplify by cancelling a b and reducing 3/12:

$=\frac{ab}{4c}$

This cannot be simplified further.
