Your DJ friend has an enormous collection of vinyl records. She knows the Beats per minute (BPM) of all the records at 45rpm but wants to know how these BPMs will change if she plays the records at 33rpm. She's figured out that the proportion of 45/33 is important but isn't sure how this will affect the BPMs. Can you write a program for this DJ so that she can easily figure out what the BPMs of her 45rpm records will be when she plays them at 33rpm?
