Answer:
[tex]\frac{1}{8}[/tex] of the whole pan
Step-by-step explanation:
Jason has 1/2 and he needs to divide this HALF by 4 to get each person's share.
That is:
[tex]\frac{\frac{1}{2}}{4}\\=\frac{1}{2}*\frac{1}{4}\\=\frac{1}{8}[/tex]
So, each of his friends will get 1/8th of the whole pan. Simple.
