Help with maths question?

I don’t know if my answer and calculations are correct and I’m really struggling, I’d appreciate any advice

\(\displaystyle \frac{5}{400} =\frac{1}{80}\) NOT \(\displaystyle \frac{80}{1}\)

Are my calculations correct? So the answer of him having 5 tickets in a 400 raffle is 1/80 chance of winning first prize?
