Rounding to ten, as that will not change the value of 880 at all.

Yes, if you are rounding to the nearest hundred. No, if you are rounding to the nearest ten.
That would depend on what you were rounding it to. If rounding to the nearest whole number, then it does not need rounding. If rounding to the nearest ten, it would be 420. If rounding to the nearest hundred, it would be 400.

365 is exactly half-way beween 360 and 370, but under the mathematical rule regarding rounding up you would probably round up to 370 (below 5 round down, 5 and above round up)
They both involve rounding numbers.
In whole numbers, rounding to the nearest ten is better. And in decimals, rounding to the nearest hundreth is more accurate.
Rounding to ten, as that will not change the value of 880 at all.
It depends on what you are rounding by. If you are rounding by ten-thousands=80000 If you are rounding by thousands=85000 If you are rounding by hundreds=84700 If you are rounding by tens=84650
Rounding to the nearest 10,000? That would be 162,000.
If rounding to the nearest ten: 795 If rounding to the nearest hundred: 750
