Question

One-third of a number yields twelve. Which equation could be used to find the number? 3n = 12 n = 12 n = -12 3n = -12

Answer 1

one third of a number n would be written as 1/3 n or n/3 so its none of the choices you've listed

it could be written as

1/3n = 12

Answer 2

`(1)/(3)n=12`

Explanation:

"One third-of a number" refers to
`(1)/(3)n`, where
`n` represents the number.

"Yields twelve" means that the given product produces 12.

So, the expression that models this problem is

`(1)/(3)n=12`

To find the number, we just have to solve for
`n`

`(1)/(3)n=12\\n=(3(12))/(1)\\ n=36`

Therefore, the number is 36.
