Answer: She ate [tex]2\dfrac{19}{21}[/tex] of the pizza pies.
Step-by-step explanation:
Pizza pizza pies left = [tex]4\dfrac37=\dfrac{7\times4+3}{7}=\dfrac{28+3}{7}[/tex]
[tex]=\dfrac{31}{7}[/tex]
In the middle of the night, Mrs. Storz ate [tex]\dfrac23[/tex] of pizza.
Pizza she ate = [tex]\dfrac{31}{7}\times\dfrac23=\dfrac{62}{21}=2\dfrac{19}{21}[/tex]
Hence, she ate [tex]2\dfrac{19}{21}[/tex] of the pizza pies.
