Answer 1

3

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.

`(8ab)/(2bc)=(8\cdot3\cdot12)/(2\cdot12\cdot4)=\boxed{3}`
