Question

what is the international rule of rounding off?​

Answer 1

Here's the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.

Answer 2

Answer:

Step-by-step explanation:

(i)if the digit just next to the last digit to be retained is less than 5, the last digit is taken as such and all other digits on its right are dropped.

ex: 1.52 = 1.5

(ii) if the digit just next to the last digit to be retained is more than 5, the last digit is increased by 1 and all other digits on its right are dropped.

ex: 1.56 = 1.6

(iii) if the digit just next to the last digit to be retained is 5, the last digit is left unchanged if it is even and is increased by 1 if it is odd.

ex: 1.65 = 1.6

     1.75 = 1.8
