Answer:54 th

Explanation:

Given

Poster has an area of
A=1\ ft^2

Size of photo is
(1)/(3)\ ft* (3)/(5)\ ft

and we know


1\ ft\ \text{is equal to}\ 0.3048\ m

so
(1)/(3)\ ft is
0.1016\ m


(3)/(5)\ ft is
0.1828\ m

So area of photo is


a=0.1016* 0.1828


a=0.01858\ m^2

ratio of area of photo and poster is


\Rightarrow (a)/(A)=(0.01858)/(1)\approx (1)/(53.819)\approx (1)/(54)

So photo will acquire
54^(th) Part of poster
