I would say "twenty four point thirty two".
Thirty-nine point two
You say 'triginta duo'

On an invitation, you would write four thirty in the afternoon as "4:30 PM." Alternatively, you can also write it in a more formal style as "four thirty in the afternoon." Both formats are clear and acceptable for indicating the time of the event.
