Im wondering what answers you will suggest?

SlightlyJaded · 05/01/2011 10:18

3 here as well. What other answer could three possibly be??

Glitterknickaz · 05/01/2011 10:18

3, as you are stating the numbers between

ChickensAreFlyingUnderTheRadar · 05/01/2011 10:19

I'd say 3 as well.

Well 3 or 5 are valid. Can't really find a justification for 4.

3 for the numbers between exclusive
5 for the numbers between inclusive

Without specifying exclusive or inclusive I'd say either answer is correct.

Hassled · 05/01/2011 10:20

My instinct is 3 but "between 1 and 5" could mean 5-1=4.

1 isnt a number? Hmm what is it then?

TheCoalitionNeedsYou · 05/01/2011 10:21

mylifewithstrangers - Between is exclusive by default.

I this children's homework? I find there are a lot of ambiguously-worded questions in my DSs homework. Annoying

i was told:

3 (2,3,4)
4 (2,3,4,5) 1 isnt a number its a primary number (still a number in my mind)
5 (1,2,3,4,5)

This is why I dont have a maths GCSE and can barely subtract.

Sorry got me thinking from the stargazing thread about astronomy if I could have my time again

I have a maths GCSE and I have never heard that 1 isnt a number Shock

TheCoalitionNeedsYou · 05/01/2011 10:23

Actually, you didn't specify that it's natural numbers only, so the answer is 'an infinite number of real numbers'.

sickoftheholidays · 05/01/2011 10:23

there are an infinite number of numbers between 1 and 5, it just depends how many decimal places you want to go down to.
but I suspect that is a gcse/alevel maths answer. If you are 6 years old, the answer is 3. I think. maybe.

TheCoalitionNeedsYou · 05/01/2011 10:26

1 is a number, so is squrt(2), so is pie, so is e, so is i, so is 1/3 and so is 0.12566664.

That is a prime, irrational, imaginary, real or whatever they are all still numbers.

1 isn't considered a prime number anyway.

mamaloco · 05/01/2011 10:28

1 is "primary number" then 2, 3and 5 are out too, which leaves 4, so just one number Confused

How many numbers between 1 and 5, the answer is an infinity.
How numbers between 1 and 5 (for school children before they learn fractions), Between so you take out 1 and 5 (doesn't matter if 1 is a primary or not Hmm), it leaves 2, 3 and 4.
