Answer: 0.3243, or 0.32 minutes per paper
Explanation:
Since the there are more papers than minutes, we know that this number will be a decimal.
You need to do 12/37 because there are 12 minutes of 37 papers. That means 12 divided by 37.
That would give you the total of 0.3243, or 0.32 if you are rounding.
