1 hour = 60 minutes        Multiply both sides of this equation by 12

12 hours = 720 minutes

 

Now we can set up this equation:

 

\(\frac{1500 \, \text{ papers}}{45\,\text{ mins}}=\frac{x}{720\,\text{ mins}}\)          and solve for x by multiplying both sides by 720 mins.

 

\(720\,\text{ mins}\,*\,\frac{1500 \, \text{ papers}}{45\,\text{ mins}}=x \\~\\ 24,000\,\text{ papers}=x\)
