Question

How do you round 12,840 to the nearest ten?

Answer 1

`12.840 ~~10`

`12,840` is already to the nearest `10`

Explanation:

Well, it depends on whether your number is twelve thousand eight hundred and forty (12 840) or `12.840.` I'm afraid I'm from the UK so I always do decimal points with a period but I know some places use commas.

If it is 12 840, then the number is already to the nearest ten as there are no digits smaller than ten (40 is a multiple of ten).

However if it is 12.840 then the nearest ten would be `10.` This is because we round up or down the digit after the tens. In this case, we would be looking at the 2 in the units. This rounds down so it stays as a ten.

Hope this helps! Let me know if I can do anything else:)
