        As spawning season approaches, the fish acquire a humpback and protuberant jaw. After spawning, they die and their carcasses provide a feast for gatherings of mink, bears, and Bald eagles.

Hello.

The correct number is 3.3125

You need to make 54/16 = 3.3125

Please let me know if this work for you.

Tito Campos is correct. For the challenges, and in real-life coding the CSS numbers need to be as exact as possible. I've seen decimal places run 10+ places. The general rule is... the more accurate, the better (so no rounding).

Keep Coding! :)
