Well, the questions aren't there, so here are the percentages:
Of the meat, [tex] \frac{3}{12} = 25[/tex]%
Of the veggies, [tex] \frac{6}{12}=50 [/tex]%
Of the cheese, [tex] \frac{3}{12} =25[/tex]%
If you can get [tex] \frac{1}{3} [/tex] of the meats, then you can get 30% of the meat, or 8.3% out of the total, or 30% of the three things you can get.
If you can get [tex] \frac{1}{6} [/tex] of the veggies, then you can get 16.6% of the veggies, or 8.3% of the total, or 30% of the three things you can get.
If you can get [tex] \frac{1}{3} [/tex] of the cheeses, then you can get 30% of the cheeses, or 8.3% out of the total, or 30% of the three things you can get.
Provide more info and I'll have a better answer :)
