I am a Physics teacher but I also teach Calculus and Linear Algebra.
In perfect Socratic style I believe that...The only true wisdom is in knowing you know nothing!!!

Hi @Alan P. can you have a look? I think there is something wrong but I cannot get it. Using proportions I got 27 but then if I check with Pythagoras it doesn't fit....

Yep, your pizza is always the same! Also your second idea is correct. The resulting ratio basically gives you the dimension of each slice (visually you can say "how big" is the slice). In terms of pizza it is like to say whether your slice is big or small. If you add a number to the denominator you have to make room for more slices inside your pizza (the number in the denominator tells you the number of slices the pizza was divided into while the numerator represents the amount of slice you received!). Although you add the same number to the numerator and so you increase the number of slices you receive their dimension is reduced leading to a reduction of the amount you....eat! It is like the donkey and the carrot: if you run faster (increase the numerator to get more slices) the carrot stays in front (because as a consequence your slices become smaller every time)!

How will you compare 2 ratios: 5/4 and 11/10 in a visual diagram form?
