The quotient of 12 and the product of 3 and 4.

1

Step-by-step explanation:

First, create an expression. Since it says "the product of", we know that 3 and 4 should be in parenthesis and are multiplied. "The quotient of" means that 12 is being divided by the product of 3 and 4. Our expression looks like this: 12 / (3*4). Now, solve! 3 times 4 is 12, so now we have 12/12. 12 divided by 12 is 1.

The answer is twelve.
