# of the day Question : 12

# 9643.715
12. Divided the number of the day with 3.55 and round
to the nearest hundredth

9643.715 divided by 3.55 =

2716.539400

That is the answer. You divide it then you go to the nearest hundredth and if the next number (tenths) is below "5" you make the hundredth number the same and change the numbers after it then you put them as "0". But if the tenth number is above the number "5" you make the hundredth number up by 1 number and you make the numbers after that "0".
