I am trying to come up with an interesting problem to show my students how the percentage units work. In their book I can only find the problems for ex: "the interesting rate has risen from 2% to 3%. How big is the increase a) in percentage unites b) in percent." What do you think of a problem like this: "Sam's wages has risen for 3,4% and Maria's wages has risen for 4,5%. How much less has Sam's wages risen compared to Marias rise? (calculate it in percentage unites and in percent)". Apart from the question if this problem is well defined, I also want to ask you, guys, if you have a more interesting problem where one can see better when and why we use the percentage units and when the percentage. Thank you in advance.

I think "percentage point" would be a more common term than "percentage unite". – peterwhy Nov 29 '23 at 19:56

Oh, yes! I am sorry. I am not so familiar at using this terminology in English. – Midica Milovanovic Nov 29 '23 at 20:00

Ask your students to solve differential equations. – MathStackexchangeIsNotSoBad Nov 29 '23 at 20:45

Also, it is interest rate (not interesting). – user58697 Nov 29 '23 at 21:24

Welcome to Math SE. FYI, in the future, questions like yours here may be better suited for the Mathematics Educators SE site. Nonetheless, before possibly posting any questions there, please first read their Help Center as to what sorts of questions are appropriate (and those which are not), as well as going through at least a few of their questions, especially those with tags applicable to what you're asking about, to get a better feel for what is, and is not, accepted there. – John Omielan Nov 30 '23 at 00:48
