Question

The time it takes to set up a circus tent varies inversely with the number E of elephants used. If 4 elephants can set up a tent in 30 hrs how long will it take 2 elephants?

Answer 1

The answer is 15 hours.

I used division to answer this question:

There are 4 elephants and 30 hour:  $\frac{4}{30}$

So: $\frac{4}{30}$ divided by 2 is $\frac{2}{15}$

So it takes 15 hours for 2 elephants to set up a tent.
