1.556621881 rounded to zero decimal place = 2
The only way to do this is by adding a zero after the 2 digit in the decimal.
When you round to 2 decimal places you will take the decimal portion which is .575 and look at the 3rd decimal place to the right which is 5. If this number is 5 or above you will round the second decimal place up 1 and if it is less than 5 you will keep it how it is. So in your case you will round the 7 up one because the 3rd place is 5 or above. Your answer will be 684.58 Hope this helps :)
That depends on what you want to round it to, like one decimal place or a whole number, as in the following examples: One decimal place: 1.7 A whole number: 2
7.446 is rounded to 7.45. Look at the number to the right of the second decimal place (or the hundredth place), if: x>= 5 then round up, x<5 then round down. Since 6 is >= 5 we round 4 up to 5.

It means to round a decimal number to its nearest hundredth place as for example 2.125 rounded to 2 decimal places is 2.13
You round to 1.0
Depends what decimal place you wish to round it to. For example, to no decimal places it is 2, to one decimal place it is 1.9, to two decimal places it 1.90 (however it is not entirely necessary to write the zero).

Look at the third decimal place. It is a 5, so it will round up the second decimal to give 0.69 as your answer.
