How do you pronounce 0,75 or 3,24?

[QUOTE=brewha]
This is a little off topic, but according to my old roomate (who is a math major and generally anal about this kind of stuff), .75 should not be pronounced “point seven five.” He is convinced that it should only be pronounced " seventy five thousandths. 3.24? Three and twenty four thousandths. Any other pronunciation is wrong.

Anyone else heard of this?

Sounds to me like he hasn’t really got to grips with the decimal system, and wants to remain fractional.
