Question

How do i write 91.009 in word form.

Answer 1

ninety one and nine thousandths 

Answer 2

first, we have the whole number, which is 91, or "ninety one." The decimal point counts as "and," and then we have the decimal itself. One place over would be the tenths place, and then the hundredths, so now we have the thousandths, so we say the whole number as it as:
"ninety one and nine thousandths"
