Question

One-third of a number yields twelve. Which equation could be used to find the number?

1/3 n= -12
1/3 n = 12
3 n = 12
3 n = -12

Answer 1

1/3n=12

this is the answer

Answer 2

1/3n=12

Explanation:

The reason why it is 1/3n=12, is because you know that the number in front of n is 1/3. By figuring that out, you have already ruled out 3n=12 and 3n=-12. Finally, you know that 12 is a positive number leaving you with 1/3n=12.
