81,215 rounded to the nearest ten thousands is 80,000
It's already there.
700 because it is over 4 so 4 and under it would be 690 but it is 8 so it is over so 5 and over changes it to 700
300
Two hundred eighty million.
It is 800.
81,215 rounded to the nearest ten thousands is 80,000
The answer depends on the degree of rounding. To the nearest unit (integer), 299.5 To the nearest ten: 295 To the nearest fifty: 275 To the nearest N : 300 - N/2

There are ten hundreds n every thousand so there are a total of one hundred hundreds in 10,000.
To the nearest unit: none (other than itself) To the nearest 5: 5 (incl itself) To the nearest 10: 10 (incl itself) To the nearest n: n, where n is any integer.
It depends on the degree to which you are rounding: To the nearest integer: 99.5 To the nearest 10: 95 To the nearest 100: 50 To the nearest n: 100 - n/2
Six thousandths in standard form is 6.0 × 10-3

When rounding to the nearest hundred, half will round down and half will round up, ie 100 ÷ 2 = 50 will round each way. → any number greater than or equal to 900 and less than 900 + 50 = 950 will round down to 900. ie any number n such than 900 ≤ n < 950 will round down to 900 to the nearest 100. Which means your [whole] number could be any of 900, 901, 902, ..., 949.
To determine if 2750 is a reasonable answer for 917 multiplied by 33, we can estimate the result using rounding. Rounding 917 to the nearest hundred gives us 900, and rounding 33 to the nearest ten gives us 30. Multiplying 900 by 30 gives us 27,000, which is close to 2750. Therefore, 2750 is a reasonable estimate for the product of 917 and 33.
