Need steps please

Answer 1

Answer:54 th

Step-by-step explanation:

Given

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

Size of photo is $\frac{1}{3}\ ft\times \frac{3}{5}\ ft$

and we know

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

so $\frac{1}{3}\ ft$ is $0.1016\ m$

$\frac{3}{5}\ ft$ is $0.1828\ m$

So area of photo is  

$a=0.1016\times 0.1828$

$a=0.01858\ m^2$

ratio of area of photo and poster is

$\Rightarrow \frac{a}{A}=\frac{0.01858}{1}\approx \frac{1}{53.819}\approx \frac{1}{54}$

So photo will acquire $54^{th}$ Part of poster
