Hint
Help VideoCorrect
Great Work!
Incorrect
If the number you are rounding is followed by numbers between:- `0 \text(to) 4:` Round the number down
- `5 \text(to) 9:` Round the number up
Method OneSince we are rounding to the nearest tens `(10)`, apply the rounding rule on the units value, which is `9`.Since `9` is within `5-9`, add `1` to the tens value and change the digits toitshe right to `0`.`73``5``9` `=` `73``6``0` Therefore, `7359` rounded off to the nearest tens is `7360`.`7360`Method TwoDraw a number line with ten parts then mark the leftmost part as `7350` and the rightmost part as `7360`
Next, mark `7359` within the number line, which should be the ninth part.
Then, mark the middle part, which indicates `7355`
For rounding off numbers, follow these rules with regards to the number line:`\text(Left of the middle mark)=\text(Rounded to the leftmost value (7350))``\text(Right of the middle mark)=\text(Rounded to the rightmost value (7360))`Since `7359` is to the right of the middle mark, `7359` will be rounded off to the rightmost value, which is `7360`.`7360` -

Correct!
Incorrect
If the number you are rounding is followed by numbers between:- `0 \text(to) 4:` Round the number down
- `5 \text(to) 9:` Round the number up
Method OneSince we are rounding to the nearest tens `(10)`, apply the rounding rule on the units value, which is `3`.Since `3` is within `0-4`, leave the tens value as is, and change the digits to its right to `0`.`46``7``3` `=` `46``7``0` Therefore, `4673` rounded off to the nearest tens is `4670`.`4670`Method TwoDraw a number line with ten parts then mark the leftmost part as `4670` and the rightmost part as `4680`
Next, mark `4673` within the number line, which should be the third part.
Then, mark the middle part, which indicates `4675`
For rounding off numbers, follow these rules with regards to the number line:`\text(Left of the middle mark)=\text(Rounded to the leftmost value (4670))``\text(Right of the middle mark)=\text(Rounded to the rightmost value (4680))`Since `4673` is to the left of the middle mark, `4673` will be rounded off to the leftmost value, which is `4670`.`4670` -

Keep Going!
Incorrect
If the number you are rounding is followed by numbers between:- `0 \text(to) 4:` Round the number down
- `5 \text(to) 9:` Round the number up
Method OneSince we are rounding to the nearest hundreds `(100)`, apply the rounding rule on the tens value, which is `5`.Since `5` is within `5-9`, add `1` to the hundreds value and change the digits to its right to `0`.`7``3``5``9` `=` `7``4``00` Therefore, `7359` rounded off to the nearest hundreds is `7400`.`7400`Method TwoDraw a number line with ten parts then mark the leftmost part as `7300` and the rightmost part as `7400`
Next, mark `7359` within the number line, which should be close to the sixth part.
Then, mark the middle part, which indicates `7350`
For rounding off numbers, follow these rules with regards to the number line:`\text(Left of the middle mark)=\text(Rounded to the leftmost value (7300))``\text(Right of the middle mark)=\text(Rounded to the rightmost value (7400))`Since `7359` is to the right of the middle mark, `7359` will be rounded off to the rightmost value, which is `7400`.`7400` -

Fantastic!
Incorrect
If the number you are rounding is followed by numbers between:- `0 \text(to) 4:` Round the number down
- `5 \text(to) 9:` Round the number up
Method OneSince we are rounding to the nearest hundreds `(100)`, apply the rounding rule on the tens value, which is `7`.Since `7` is within `5-9`, add `1` to the hundreds value and change the digits to its right to `0`.`4``6``7``3` `=` `4``7``00` Therefore, `4673` rounded off to the nearest hundreds is `4700`.`4700`Method TwoDraw a number line with ten parts then mark the leftmost part as `4600` and the rightmost part as `4700`
Next, mark `4673` within the number line, which should be between the sixth and seventh part.
Then, mark the middle part, which indicates `4650`
For rounding off numbers, follow these rules with regards to the number line:`\text(Left of the middle mark)=\text(Rounded to the leftmost value (4600))``\text(Right of the middle mark)=\text(Rounded to the rightmost value (4700))`Since `4673` is to the right of the middle mark, `4673` will be rounded off to the rightmost value, which is `4700`.`4700` -

Excellent!
Incorrect
If the number you are rounding is followed by numbers between:- `0 \text(to) 4:` Round the number down
- `5 \text(to) 9:` Round the number up
Method OneSince we are rounding to the nearest thousands `(1000)`, apply the rounding rule on the hundreds value, which is `3`.Since `3` is within `0-4`, leave the thousands value as is, and change the digits to its right to `0`.`7``3``59` `=` `7``000` Therefore, `7359` rounded off to the nearest thousands is `7000`.`7000`Method TwoDraw a number line with ten parts then mark the leftmost part as `7000` and the rightmost part as `8000`
Next, mark `7359` within the number line, which should be between the third and fourth part.
Then, mark the middle part, which indicates `7500`
For rounding off numbers, follow these rules with regards to the number line:`\text(Left of the middle mark)=\text(Rounded to the leftmost value (7000))``\text(Right of the middle mark)=\text(Rounded to the rightmost value (8000))`Since `7359` is to the left of the middle mark, `7359` will be rounded off to the leftmost value, which is `7000`.`7000` -

Nice Job!
Incorrect
If the number you are rounding is followed by numbers between:- `0 \text(to) 4:` Round the number down
- `5 \text(to) 9:` Round the number up
Method OneSince we are rounding to the nearest thousands `(1000)`, apply the rounding rule on the hundreds value, which is `6`.Since `6` is within `5-9`, add `1` to the thousands value and change the digits to its right to `0`.`4``6``73` `=` `5``000` Therefore, `4673` rounded off to the nearest thousands is `5000`.`5000`Method TwoDraw a number line with ten parts then mark the leftmost part as `4000` and the rightmost part as `5000`
Next, mark `4673` within the number line, which should be between the sixth and seventh part.
Then, mark the middle part, which indicates `4500`
For rounding off numbers, follow these rules with regards to the number line:`\text(Left of the middle mark)=\text(Rounded to the leftmost value (4000))``\text(Right of the middle mark)=\text(Rounded to the rightmost value (5000))`Since `4673` is to the right of the middle mark, `4673` will be rounded off to the rightmost value, which is `5000`.`5000`
