As shown in the figure, in △ ABC, ad: DB = 2:1, be: EC = 3:1, CP: FA = 4:1, then △ dep is a fraction of the area of △ ABC

First of all, you didn't make it clear. I guess it's because D, e and P are in AB, BC and Ca respectively. Second, you marked a P as f
Let s △ ABC = 1
So s △ ADP = 2 / 15
S△BED=1/4
S△CEP=1/5
S△DEP=5/12
