Divide the number of the day by 3.55 and round to the nearest hundredth.
*As an example, we'll use the number 2364.578*
1 - Divide the number of the day by 3.55 (2364.578÷3.55=666.07830985915).
2 - We only need to know the whole number (666) and the tenths, hundredths and thousandths (0.078). So that leaves us with the number 666.078.
3 - The question states we have to then round to the nearest hundredth, which in this case, is the 7. To determine if it will stay as 7 or go onto 8, we need to use the next place value beside it (the thousandths). If the number that determines whether you round up or down is between 0-4, you round down. If the number is between 5-9, you round up. Since the thousandths place has an 8, we'll round the hundredth up. We end up with 666.08.
4 - We've done all the steps so the answer to this would be 666.08.
