Incorrect
Loaded: 0%
Progress: 0%
0:00
If the number you are rounding is followed by numbers between:
- 0 to 4: Round the number down
- 5 to 9: Round the number up
First, mark the decimal places to remain, as well as the digit to its right.
Since we are rounding to two decimal places, apply the rounding rule on the thousandths value, which is 9.
Since 9 is within 5−9, add 1 to the hundredths value, then remove any other digits to its right.
In this case, the hundredths value will become 10, so we will take the 0 as the hundredths value and add 1 to the tenths value.
Therefore, 7.499 rounded off to two decimal places is 7.50.

If the number you are rounding is followed by numbers between:
- 0 to 4: Round the number down
- 5 to 9: Round the number up
First, mark the decimal places to remain, as well as the digit to its right.
Since we are rounding to four decimal places, apply the rounding rule on the hundred thousandths value, which is 9.
Since 9 is within 5−9, add 1 to the hundredths value, then remove any other digits to its right.
In this case, the ten thousandths value will become 10, so we will take the 0 as the ten thousandths value and add 1 to the thousandths value.
| 0.00699 |
= |
0.0070 |
Therefore, 0.00699 rounded off to four decimal places is 0.0070.
