If the question is about a PERSON or KOALA, or some RABBITS or some CAMELS, and the approximation comes out to be...

3456.789

Is it ok to just say 3456 whole people/koalas/rabbits/camels? I mean, this is pedantic...but...should I just round and say: 3457 (nearest whole person)?

Thanks

What was the question??

Usually i find questions aren't designed to have decimals?

Whenever working with questions about people, koalas, rabbits or camels or anything of the sort, always round up.

If you round down, you are not taking in to account the need for the extra bit you ignored.

Decimals are very common.

Decimals are very common.

Grr. My Head maths teacher designs most of our question to result in whole numbers when it comes to this.

EDIT: Wouldn't the question say how to round it?

No, some questions won't say anything.

My maths teachers (head marker) says both answers would be accepted.

My teacher said this to as long as you write how you rounded it (e.g. 3.d.p) but he said that it is unlikely to get questions like this which don't tell you.

Round it, but in the last two steps go like this:
=3456.789...
=3457
There will be 3457 X after Y years.
