Small numbers can sometimes be a problem for students. How do you say those darn things?

It’s simple:

 
– For decimals, just say each digit in the series. The period (NOT the comma!) is read “point”.
The number 0 is read “zero”, “naught”, or “oh”.

1.23 is “one point two three”
75.09 is “seventy-five point oh nine”
0.2 is “zero point two”

– They’re the same in front of units, where no preposition is used:

The car is one thousand, three hundred (and) forty point eight millimeters long (1,340.8mm)
She is one point eight meters tall (1.8m)
