Explanation:
Hello! Remember you need to write complete questions in order to get good and exact answers. Here we know nothing about the students so I can only help you providing the correct steps to find the product of a number and eight is 104:
Let that number be [tex]n[/tex], then the statement can be written in a mathematical language as follows:
[tex]n\times 8=104 \\ \\ \\ \text{Dividing both sides by 8:} \\ \\ \frac{n\times 8}{8}=\frac{104}{8} \\ \\ \boxed{n=13}[/tex]
Finally, the unknown number is 13
