Inner tube sizing question

Hi guys,

Bit of a noob query this! I've decided I really need to learn how to do some maintenance/p*nct*re repairs myself, so bought a kit and dug some spanners out of Mr M's tool kit.

However, I have fallen at the first hurdle as I can't work out which tubes I need to buy! The numbers on the tyre are as follows: 700x38 40-622.

I can't find anything with these exact numbers on them - am I right in thinking that tubes fit a RANGE of different tyres (eg there were some on Wiggle that had '700x35-47' would these be right??)

Thanks for any help!!
