Now as for the problem

bahrom7893 · Answer

Suppose class ordered 3 pizzas of the same size: 1 and 1 and 1 (let's call a pizza a 1)
five twelfth of a pizza is:
(5/12)*1 = 5/12. Now if they had 5/12 th of each pizzas then it would've been:
(5/12)+(5/12)+(5/12) = 3*(5/12)

That's the same as:
15/12 = 5/4.
