Scala Spark - Mapping values of tuple to single

I'm trying to map some data looking like this: ("en",(20340,302)) (so a tuple of a string and a tuple: (String, (Int, Int)) ) into data looking like this: (String, Int/Int) (so the example output would be ("en", 67 ) ). What is the syntax for this?

val new = old.map(a,(b,c) => (a, b/c) )

is what I tried to do, is not working though.

val new = old.map { case (a,(b,c)) => (a, b/c) }

Which is syntactic sugar for:

val new = old.map(t => t match {
  case (a,(b,c)) => (a, b/c)
})

or an uglier version: 

val new = old.map(t => (t._1, t._2._1/t._2._2))
