Answer:
Mike ate [tex]\frac{3x}{16}[/tex]th portion of the pizza on Friday.
Step-by-step explanation:
Let us consider the quantity of pizza = x
If Mike left [tex]\frac{3x}{8}[/tex] of the pizza in the refrigerator.
On Friday he ate [tex]\frac{1}{2}[/tex] the portion of pizza he ate = [tex]\frac{3x}{8}\times \frac{1}{2}[/tex]
= [tex]\frac{3x}{16}[/tex]
Therefore, Mike ate [tex]\frac{3x}{16}[/tex]th portion of the pizza on Friday.
