Answer:
3.18564
Step-by-step explanation:
In 3.18563809487,
the 1 represents the tenths place,
the 8 represents the hundredths place,
the 5 represents the thousandths place, and
the 6 represents the ten thousandths place,
the 3 represents the hundred thousandths place
Tne next digit is 8 because 8 is greater than 5, we must round up the 3.
So, to the nearest hundred-thousandths place, we have 3.18564.
