Answer 9

Still no, but at least your moving in the right direction.
It should make sense that more cows means less time is needed to eat the grass...

Answer 10

5 days

Answer 11

and how did you come to that conclusion?

Answer 12

100/20=250/x, x=50

Answer 13

250/50 =3

Answer 14

formulation is always better than guessing :)

Answer 15

of course I don't know what you did above...
20/100=x/250
x=5

Answer 16

250/50 = 5

Answer 17

is it 5 days ?

Answer 18

yes, 5 days
You set up the problem correctly.

Answer 19

20/100=x/250

Answer 20

in the previous thread was it really 17.5 units approx.

Answer 21

That was a rather different question...

Answer 22

yh, i know

Answer 23

i think i'm drunk

Answer 24

intoxicated rather

Answer 25

sorry, i'm sleepy nw. It's been a gr8! xmas! xx happy Boxing Day! xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Answer 26

cheers

Answer 27

40?

Answer 28

it's not 5

Answer 29

No, it's 8 :/
100 cows eat the same in 20 days that 250 do in x days, so
100(20)=250x
x=8
that's what I get for staying up too late.
