Step 3:            6.24 is the number rounded to two decimal places.

Example:

Round off the subsequent number to two decimal places.

6.2385

6.2385

Solution:

Step 1:            5 is the number to the right of the 3rd decimal place.

Step 2:            5 is equivalent to 5, so drop the 5 and add one to the number within the third decimal place (8 + 1 = 9).
