It is a question aimed at establishing whether or not you understand the process of rounding.
To round to the nearest whole number the tenths digit (the one after the decimal point) is the deciding digit whether to round up or down - if it is less than 5 round down, otherwise round up. The tenths digit of 9.13 is 1 which is less than 5 so round down 9.13 → 9 to the nearest whole number.
If you are rounding to the nearest tenth, then since the number next to the tenth is 5 or higher, so it would round to 0.1, and if you round to the nearest one then since the number next to the ones place is 4 or less, it is rounded down to 0
Look at the digit after the ones digit - the tenths digit; if it is 5 or more round up, otherwise it is less than 5 so round down. The tenths digit (the one after the decimal point) is a 9 so round up: 986.91 → 987 to the nearest whole number.
4.489
To the nearest hundred: 400 To the nearest ten: 400 To the nearest one: 396
To round the number 673,807.3865 to the nearest one, we look at the digit in the one's place, which is 7. Since 7 is greater than or equal to 5, we round up. Therefore, the number rounded to the nearest one is 673,807.
Rounding this number to the nearest whole number 1.123, I answered 'one' one time.
51 Fifty one rounded to nearest whole number
I assume you mean to round it to the nearest whole number. In this case, you would round it up to 34
To the nearest hundred: 400 To the nearest ten: 440 To the nearest one: 435
It's already there.
We could have used that missing number. In general, the least whole number that will round to the nearest hundred is x50 of the previous one. 650 is the least whole number that will round to 700
To the nearest hundred: 300 To the nearest ten: 250 To the nearest one: 251
To the nearest whole number, 4.
217.8 the same as asking to round a number to one decimal place.
divide the smaller number by the bigger one and round to the nearest whole number
To round to the nearest whole number the tenths digit (the one after the decimal point) is the deciding digit whether to round up or down - if it is less than 5 round down, otherwise round up. The tenths digit of 9.13 is 1 which is less than 5 so round down 9.13 → 9 to the nearest whole number.
