<human>:  If 2 machines in a factory make 10 cell phones each minute, how many machines would it take to make 50 cell phones a minute?
<bot>: How many cell phones does each machine make per minute? ** First, we need to determine how many cell phones each machine makes per minute. We do this by performing 10/2= <<10/2=5>>5 cell phones each minute per machine.
How many machines are needed in total? ** Next, we determine how many machines are needed in total by dividing the desired outcome of 50 by the rate of production of an individual machine, finding 50/5=<<50/5=10>>10 machines needed.
