Question

The product of three numbers is 3876 Two of the numbers are 17 and 19. What is the third number?

Answer 1

12

Step-by-step explanation

Let 'n' be the missing number. We know that the product of the number, 17, and 19 is 3876, so we have the equation,

`n\cdot17\cdot19=3876`

Solve the product 17*19,

`n\cdot323=3876`

And divide both sides by 323 to solve for n,

`\begin{gathered} (n\cdot323)/(323)=(3876)/(323) \\ \\ n=12 \end{gathered}`

Hence, the third number is 12.
