Forty million
Eighteen billion.
The number 400 is written in words as four hundred.
You write the number in words >:D
Write out the number 32 as thirty two (in words).

Ok so im only 12 but im AMAZING at math. Im really not ttrying to brag but its just my better subject. when u write a decimal all you this the trick. 54.987 you startwith the firs number to the right of the decimial. that's called the tenths place NOT tens tenthS. the second number to the right is 8 is called the hundredths. Finially the last number 7 is called thousandths. i hope that helped
