In every question, you will need to round off to ONE or TWO decimal places depending on the instruction.

This is what you must do:

If rounding to ONE decimal place, always look at the SECOND digit after the comma.

If this second number is 5,6,7,8 or 9, increase the first number by 1.
If this second number is 0,1,2,3 or 4, DO NOT change the first number,just leave it as it is.

If rounding to TWO decimal places, always look at the THIRD digit after the comma.

If this third number is 5,6,7,8 or 9, increase the second number by 1.
If this third number is 0,1,2,3 or 4, DO NOT change the second number,just leave it as it is.
