I am realising that the question can be asking two things. Q1) what is 720 rounded to the nearest 10? A1) 720, as 720 is divisible by 10 Q2) A number has been rounded to the nearest 10, and the answer is 720, but what was the original number? A2) the number could have been any number between 715 and 724.99999.... hope it helps

The equivalent of 720 as a Roman numeral is DCCXX
It is at the nearest 10, so 210 is the answer.
It is already at the nearest 10, so there is no change. It is 439200.
It is already at the nearest 10, so the answer is 340.
It is already at the nearest 10, so there is no change. It is 439200.
Round 412 nearest 10? Answer: 400 Reason: You play with last 2 digits of 412 (because he asked to round nearest 10; i.e. 12, now 11-14 is nearest to 10 so round to 10. So, 412 nearest to 10 is then 400.

40 is divisible by 10, so it is already at the nearest 10 and does not need to be changed.
810 is divisible by 10, so it is already at the nearest 10.
30 is divisible by 10, so it is already at the nearest 10.
453 + 56 = 509 so nearest 10 is 510
As it ends with a five, it will round up, so 30 is the nearest 10.
because 199 rounded to the nearest 10 is 200, so 199 to the nearest 100 is 200.. Because 200 is both a multiple of 10 and 100.
