A legal firm offers some services "pro bono", which means that they work for clients free of charge. The legal firm accepted 2% of its cases pro bono last year. What is the total number of cases they completed if they accepted 252 pro bono cases?
252 is [tex]\frac{1}{50}[/tex] of the whole amount of cases, because 252 is equal to 2% of all cases that this legal firm the completed, and [tex]\frac{100}{2}[/tex] is equal to 50.
