2811 rounds down to 2800
18 is an integer, so no rounding is necessary. You can indicate the precision of the number, if you wish, using zeroes: 18.00.
$266.67 (using the usual rounding rule of rounding up if the value is 5 or greater)
if the number is less than 5 round toward the number 1 if the number greater than a 5 round toward the number 9
rounded to the nearest hundredth is 3.57. Rounded to the nearest tenths is 3.6. Rounded to the nearest unit is 0
Using rounding rules, 13 is the nearest kilo.
2811 rounds down to 2800
The answer will depend on the degree of rounding. To the nearest tenth, (using the IEEE standard for rounding 5s to even) it is 2.4 whereas to the nearest tens it is 0.

You look at the digit in the hundred thousands position, which is a 1. That will cause a rounding down of the overall number to 14000000.
Using the standard rules for rounding, 35 will be rounded to 40 as the nearest 10.
The question can not be answered because you did not specify to what level of rounding to use. Please restate the question. If you round to the nearest integer, the answer is 47.
That's rounding to the ten thousand place. 7840000
