Explanation:

For ham:
____________________________________
[tex] \frac{20}{60} = \frac{2}{6} [/tex] = (2÷2)/(6÷2) = [tex] \frac{1}{3} [/tex] ,
{Note: Sample of "60" ; Refer to "20" for "ham" on the table.}.
______________________________________________
[tex] \frac{1}{3} *1200[/tex] = 400 .
{Note: "1200 students" at the school; as given in the problem.}.

The answer is: "400 pizzas".
_______________________________________________________
The assumption is that each student is gets to eat ONE WHOLE PIZZA for one's self ; or at least GAIN — or OBTAIN — ONE WHOLE PIZZA for oneself—each. If EACH STUDENT is going to "eat less", or "obtain" less"; or "be allotted"—LESS THAN ONE WHOLE PIZZA EACH; the answer: "400 pizzas" would decrease.

{Note that there are no such specifications given in the problem; as such, I mentioned "one whole pizza each"; or "be allotted one whole pizza each" (that one could, for instance, take home the rest for ONESELF).}.
