    \(\dfrac{8}{x} = \dfrac{12}{18} \) \(x = \dfrac{8 \times 18}{12} \) \(x = 12\)

    Are you serious? Was this a challenge even?

    He was correct. But you know what else? I was correct, too, even before he came on.

    This challenge is a thinly disguised way of getting people to your homework. Just call every problem a challenge, and someone will take it on. After a while, the entire homework assignment has been done.

    We must show work because the homework assignment requires it.

    So, why even do it then? What is your reasoning behind that? If they aren't willing to even ask it as a question, why do you still give them an answer? @mathstudent55

    I am hoping she at least learns something. I don't just give a final answer. I solve the entire problem step by step. She has the option of following the solution and learning something from it.
