Question 205968: Need help with a word problem please.
A machine produces 195 bolts in 20 minutes. At the same rate, how many minutes would it take to produce 312 bolts?
Thank you
My try: I think this is a proportion, but not sure how to set it up.

You are right, it is a proportion! This question is purely a ratio problem. Your ratio is (195 bolts)/(20 minutes)=(312 bolts)/(X minutes)

Cross-multiplying and solving for x, you get 32 minutes.
