Answer:
(C) 1/4 of the pie.
Step-by-step explanation:
Given that Fernando had 3/8 of a pumpkin pie left.
So, the remaining pie= 3/8 of a pie.
As Fernando ate 2/3 of the remaining pie, so,
the portion of a pie that Fernando ate = 2/3 x 3/8 of a pie = 1/4 of a pie.
So, Fernando ate 1/4 of a pie.
Hence, option (C) is correct.
