Six machines, each working at the same constant rate, together can complete a certain job in 12 days. How many additional machines, each working at the same constant rate, will be needed to complete the job in 8 days?
This question is off of the GMAT Prep test I took.
Can someone please walk me through this one? I think I'm getting thrown off because there's 6 individual units working, rather than 1 and another, i'm going in circles in my head. Thank you!
