how would you write 9.001 as a faction?

9.001
= 9 + 0.001
= 9 + 0.001 x 1000/1000
= 9 + 1/1000
= 9 1/1000

as a mixed number: 9 1/1000

as an improper fraction: 9001/1000

9 1/1000.

Its 9 and 1/1000.

To write any decimal in fraction format, find what place the decimal number is written in. Since there are 3 digits (after the decimal) in 9.001, the very last digit is the "1000th" decimal place. It can be written in two ways, either written as a mixed fraction such as 9 and then 1/1000. But, if your teacher is not asking for them to be written in mixed fraction format, it can be written as 9001/1000

Hope this helps.
