Question

A chef can make 12 omelets in one our. what is the rate of omelets per minute?

Answer 1

there are 60 minutes in one hour, so you would divide 12 by 60

they make 0.2 omelettes a minute

Answer 2

Set up your equation to cancel out units you don't want and introduce units that you do...

(12o/hr)(hr/60min)=0.2o/min

So the chef can make 1/5 of an omelet per minute
