Answer:
3
Step-by-step explanation:
You want to evaluate the expression (8ab)/(2bc) for a=3, b=12, c=4.
Evaluation
Put the values where the corresponding letters are and do the arithmetic. Here, some factors are obviously cancelled, simplifying the problem.
[tex]\dfrac{8ab}{2bc}=\dfrac{8\cdot3\cdot12}{2\cdot12\cdot4}=\boxed{3}[/tex]
