Subject: case when when

Hi all

I am just wondering how can we make two cases belong to the same bunch
of code. I tried to do it like c but it did not work. it is like this in
c

switch(x)
{
case 5:
#do bla bla
break;
case 7 : case 9:
#do bla bla
break;
default:
#bla
}

however, I tried to do the same way in ruby but it did not work.
case x
when 5:
#do bla
when 7: when 9:
#do bla bla
else
#bla
end

I know that when provides conditions and I can use them but I am just
wondering what is the way because i did not find it in books and online

regards
