If a hen and a half lays an egg and a half in a day and a half, how many hens that are better by half lay a score and a half in a week and a half?

 

I am an evil girl.

 

The major part of the problem is translating it into mathematical notation.

3

 

..

Rounding up to the next whole number of hens, yes. Of course, the posing of the problem seems to have no objection to fractions of hens leading a happy, independent existence, so perhaps it should be 20/7, or two and six sevenths of a hen.

expressed or not, part of correctly solving word problems is applying it to real life. in real life you cant have 6/7 of a hen.

Arguably that particular rule of real life doesn't apply to this problem, since the original wording of the problem has no problem with the existence of a hen and a half.

I agree with 3, if you round a week and a half down from 10.5 days to 10 days.

Why would you do that?

can it be like this

 

If 3/2hens give3/2eggs in aday

 

the egg would be given by 1hen

 

hens 14 eggs would be given by 14 hens

 

Hence 13 hens are better

lol

 

Should I mention my answer of 3 was a complete guess?
