Spark RDD find ratio of for key-value pairs

My rdd contains key-value pairs such as this: (key1, 5), (key2, 10), (key3, 20),

I want to perform a map operation that associates each key with its respect ratio in the entire rdd, such as this: (key1, 5/35), (key2, 10/35), (key3, 20/35),

I am struggling to find a method to do this using standard functions, any help will be appreciated.
