Answer:
The answers to the question are
The fraction that names all of the oatmeal bar halves is [tex]\frac{1}{2}[/tex]
The fraction that names all of the oatmeal bar pieces obtained by cutting the the bar halves into two equal pieces is [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
To answer the question, we note that there are 5 oatmeal bars, and since each bar is cut in half, we have the fraction that names all of the oatmeal bar halves is
[tex]\frac{1}{2}[/tex]
If Lucy further cuts each part of the oatmeal bar into 2 equal pieces to share with friends, then the fraction that names all of the oatmeal bar pieces is
[tex]\frac{1}{4}[/tex]
