____ classrooms per minute

Identify amount and time: Step $1$ : Identify the amount of classroom mopped and the time taken. $\newline$ Amount mopped = $\frac{1}{3}$ classroom $\newline$ Time taken = $5$ minutes
Calculate mopping rate: Step $2$ : Calculate the mopping rate using the formula: Rate = Amount mopped $\div$ Time taken. $\text{Rate} = \frac{1}{3} \div 5$
Simplify division: Step $3$ : Simplify the division to find the rate per minute. $\newline$ Rate = $(\frac{1}{3}) \div 5 = (\frac{1}{3}) \times (\frac{1}{5}) = \frac{1}{15}$
