ANSWER
12
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,
[tex]n\cdot17\cdot19=3876[/tex]Solve the product 17*19,
[tex]n\cdot323=3876[/tex]And divide both sides by 323 to solve for n,
[tex]\begin{gathered} \frac{n\cdot323}{323}=\frac{3876}{323} \\ \\ n=12 \end{gathered}[/tex]Hence, the third number is 12.
