I was wondering if someone could explain how to think through this problem. It is really hurting my brain :wink:

If two typists can type two pages in two minutes, how many typists will it take to type 18 pages in six minutes?

Here's a similar problem.

3 hens lay 3 eggs in 3 days. How many eggs are laid by 6 hens in 9 days?

3 hens lay 6 eggs in 2 days.

3 hens lay 3 eggs in 1 day.

1 hen lays 1 egg in 1 day.

6 hens lay 6 eggs in 1 day.

6 hens lay 54 eggs in 9 days.
