OK, I understand. Give me the number to be rounded, and I'll do that.
20,000 --------------------------------- You need to specify a value such as ones, tens, hundreds, thousands, or ten-thousands. To get the greatest value by rounding you would do all of these, compare them and pick the greatest. 22,000 is greater than 20,000 and you get this by rounding to the thousands place.
1000 x 40 = 40,000
When rounding a number, you look at the digit immediately to the right of the place you are rounding to. If that digit is 5 or greater, you round up by adding one to the digit in the rounding place. If it's less than 5, you leave the rounding place digit unchanged. All digits to the right of the rounding place become zero (if rounding to a whole number) or are dropped (if rounding to a decimal).

90-80 is 10.

To get the greatest value by rounding you would do all of these, compare them and pick the greatest. 22,000 is greater than 20,000 and you get this by rounding to the thousands place.
1000 x 40 = 40,000
That's correct if rounding to the second greatest place value, but not the greatest. The greatest place value in a three digit number is the hundreds place. 849 rounded to the nearest hundred is 800.
When rounding a number, you look at the digit immediately to the right of the place you are rounding to. If that digit is 5 or greater, you round up by adding one to the digit in the rounding place. If it's less than 5, you leave the rounding place digit unchanged. All digits to the right of the rounding place become zero (if rounding to a whole number) or are dropped (if rounding to a decimal).
The greatest number that can be rounded off to 90 is 94. When rounding a number to the nearest 10, you look at the digit in the tens place. If the digit in the ones place is 5 or greater, you round the tens place up by 1. In the case of 94, the digit in the tens place is 9, and the digit in the ones place is 4, which is less than 5. Therefore, when rounding 94 to the nearest 10, it becomes 90.
It depends on which place you are rounding to. If you are rounding to the tenths place, 17.15 rounds off to 17. If you are rounding to the hundredths place, 17.15 becomes 17.2.
The greatest number to round off 80,000 depends on the level of precision required. If rounding to the nearest ten thousand, the greatest number would be 90,000. If rounding to the nearest thousand, the greatest number would be 81,000. If rounding to the nearest hundred, the greatest number would be 80,100.
