I think you could try to multiply all three of the first prism and then multiply all three of the second prism. Then you can compare both of them to each other, and there will be a difference.
Start off with a chart (you don't really need to but it helps)
Piano lessons 5,10,15,20,25,30
Cooking Classes 6,12,18,24,30
every 30 days, you have both lessons so you will have them on the 60th day
84 the process is shown in the following picture
193/990 Would be the answer. If you want the steps to find it, just ask.
