How about to say 4,7? Thanks Andrei!

четыре целых семь десятых

That's the way to say 'four point seven'? The meaning of целых, десятых here ? Thanks a lot

Yes, that's the way of spelling 4,7
You also could say shortly and more simple: четыре и семь
целых means whole part of a number
десятых means fractiona (decimal fraction) of a number

Thanks Andrei, really appreciated! Good day!
