47900 could round down to 47500 but it says to the nearest 100.
48100 could round up to 48500 but as above.

Just ignore the 10s.

I read it that each number you choose must round to 48000 as the nearest 1000, 48000 as the nearest 100 but must not round to 48000 as the nearest 10.

This is correct
anywhere from 48006 to 48049 and anywhere from 47951 to 47994 should work for this answer.

But none of the above are rounded to the nearest 100.

The answer is 47900 and 48100.

I got the same. Is that officially the answer then?

I believe yourself and myself are reading the question in a different manner.

Each number MUST round to 48000 when rounded to the nearest 1000
AND
round to 48000 when rounded to the nearest 100
BUT NOT
round to 48000 when rounded to the nearest 10.

How did you read the question?

In your answer 47900 rounded to the nearest hundred is 47900, not 48000.

After thinking about it a lot and even had my 10 year old look at it.

It seems from my thinking its 47900 as to round up to 48000.

But the second answer I think is wrong as it would be 48600 to round to 49000.

Its worded very strange, I have had a few with my daughters home work and you end up smashing your head on the table trying to work it out.

Not sure what it is with education these days, but some of the questions they put across are very convoluted.

In your answer 47900 rounded to the nearest hundred is 47900, not 48000.

But they also asked for it to be rounded to the nearest 1000, the nearest thousand rounding up from below 48000 is 47900 and the nearest 100 would be 100 if ignoring the 10`s

To have a number higher to round down from 48000 would be 48100 to equal the 100's and 1000's units.

Ignore the 00's

48 could round up to 50 and 48 could round down to 40.

So another answer could be 50,000 and 40,000.

Its because they ask for the nearest thousand rounding is the problem, if it was just 100's no problem but as they ask for both its very confusing. :confused:

Itchy, in what world do 47900 rounded to the nearest hundred ever come out as 48000?
Its 47900 to the nearest hundred.

The question asked for two numbers, it didn't state that there are ONLY two numbers.
There are a range of numbers, both above and below, thus why they asked for one of each, knowing the answer would demonstrate some idea of the range, rather than two specific numbers making the correct answer.

Lol Itchy...your comprehension is poor man.

48 could round down to 40 and 48 could round up to 50.

So another answer could be 40,000 and 50,000.

Right, so it's trolling time?

Question states it has to round to 48k (rather than 49k) so both answers - 47900 and 48100 round up and down, are higher and lower than 48k and do not rely on a 'tens' value to get there, thus both are correct from my point of view. Stupid question in any case, disappointed to have been sucked into it.

What do you mean sucked in?
On your third post, you've been sucked in?
and unless No Insults.

47900, rounded to nearest hundred is 47900
thus is not correct

But rounded to the nearest 1000 would be 48000. :confused:

Its one of them questions. :mad:

No it's not. It's really straightforward.

Like I said, you just can't comprehend it. I'm afraid it says more about you than the question.
