Answer:
[tex]8\frac{1}{3}[/tex]
Step-by-step explanation:
A whole spinach cassarole can be thought of as 100%. If Sam eats 3/4's of it then only 25% of it remains. Of that 25% Jackie and Alicia split that 25% to get 12.5% each. Jackie only eats 2/3's of her portion so now you just take 2/3 of 12.5.
The math looks like 2/3 * 12.5 = 8.333333333%
