I would don't really have the answer to this question maybe try rewording it
Both of these values are the same, so the number sentence would state:
7.17 = 7.170
You can place any number of zeros to the very end on the right side (when there is a decimal point) without changing the value of the number.
7.1700000 = 7.17 also
I think it is 4 out of 5 but i dont know the number to the nearest thousanths
but i hope this helps
