There is no universal "better". Rounding off is a trade-off between reducing the accuracy and simplifying calculations. Also, if there are other numbers in an addition that are rounded to the nearest hundred, there is no point in rounding your number to the nearest ten.
You can not add irrational numbers. You can round off irrational numbers and then add them but in the process of rounding off the numbers, you make them rational. Then the sum becomes rational.
You can round off to any values such as the nearest odd number or the nearest tens or hundreds etc.
by rounding off the numbers
The rounded off number of 1.875 depends on the level of precision required. If rounding to the nearest whole number, the rounded off number of 1.875 is 2. If rounding to the nearest tenth, the rounded off number is 1.9.
steps rounding off number
Any number greater than or equal to 745 but less than 755 can be rounded off to 750. This is because when rounding to the nearest 10, any number 5 or greater in the ones place will round up. Therefore, numbers like 746, 747, 748, 749, and 750 can all be rounded to 750.
45 is the smallest number that rounds to 50
Look at the place you are rounding off. Look at the number to the right of it. If the number to the right is 4 or less, the rounding value stays the same and every digit to the right of it goes to zero. If the number to the right is 5 or greater, the rounding value goes one higher and every digit to the right of it goes to zero.

In whole numbers, rounding to the nearest ten is better. And in decimals, rounding to the nearest hundreth is more accurate.
Rounding off is a important part of mathematics and a very handy tool for everyday life.
It depends what you're rounding off to. If you're rounding off to the hundredths, you get 9.86 If you're rounding off to the tenths, you get 9.9 If you're rounding to the whole number, you get 10

Im not sure actually. But rounding to the nearest number means its easier probably.
