Both. (I prefer twenty ten but find myself saying two thousand ten most often!)
2003 and 21/1000 or 2003.021
Ten thousand and twenty-two
10.0022
35.0022 is thirty-five and twenty-two ten-thousandths.
Twenty two and ninety two ten thousandths.
The X is ten. Two XX's would be twenty. Half an X, a V, would be five.
No ten twenty-fifths is the same as two fifths
twenty three divide ten is two point three
three hundred twenty-four thousand five hundred twenty-two and twenty-four ten thousandths
two hundred twenty and twenty two ten thousandths
Becuase two times ten is twenty and two times eleven is twenty too!
Either twenty ten or two thousand and ten.
