The question has provided the answer. The fraction is 8/13 or eight thirteenths.
Total number of parts is 25 therefore each part is 4 pounds, so your answer is 40, 52 and 8.

1 and 13
13 lines passing through the center will create 26 pie-shaped parts. Now if you need them to be equal parts, I'm not sure about that one.
2.6
It does not divide evenly, but if you were trying to get an exact answer, it would equal 26.9230769.
No, It does not have bilateral symmetry because we cannot divide into two equal parts as "Bi" means two. For Ex:- 1331 = 13|31
It is 13/18.
the simplest form of that fraction is 1/6. divide 13 by 13 is equal to 1 and divide 78 by 13 and you get 6.
It doesn't make sense to divide by zero.
8/13
Divide both parts by 9, as they are common factors. That gives you 8 and 13.
C = 2 pi r (divide by 2pi to both sides) C/2pi = r (substitute 13 pi cm for C) r = (13 pi cm)/(2 pi) = (13/2)(pi/pi) cm = 6.5 cm
