Rounding Off:

When there is a remainder in division, the remainder might be written as a fraction or rounded off. While rounding off, the subsequent rules should be applied:

Step 1: Observe the digit to the right of the digit being rounded off.

Step 2: If it is less than 5 then drop the digit.

If the digit is 5 or higher then add 1 to the digit being rounded off.

Step 3: Write the new rounded number.

Example:

Round off the subsequent number to two decimal places.

Solution:

Step 1: 3 is the number to the right of the 2nd decimal place.

Step 2: 3 is less than 5 that why it drop the digit.

Step 3: 3.47 is the number rounded to two decimal places.
