How did you get that?

anonymous · Answer

1000 times 20

sleepyjess · Answer

First off, I would find how much of a container it take for 1 rat, for 1 day.

anonymous · Answer

but they were 3 variable which confuses me =.= im sorry

sleepyjess · Answer

Ok, 1 container = 1000 rats for 20 days. To find 1 rat for 2 days, what would you do?

sleepyjess · Answer

Ah whoops, first find 1000 rats for 1 day

anonymous · Answer

erm.. 1/20 container ?

sleepyjess · Answer

Yep, which equals .05. Now divide .05 by 1000 to find how much of a container for 1 rat for 1 day. Or you can also move the decimal point to the left by 3.

ok thanks!

sleepyjess · Answer

What do you get now?

sleepyjess · Answer

Remember, that is only for 1 rat for 1 day. We need 550 rats for 400 days.

anonymous · Answer

i'll just multiply 550 and 400 right ?

sleepyjess · Answer

Multiply .00005 by 550, then 400 and that is the answer :)

anonymous · Answer

yup ok, thank you :)
