Given ratio of weight of any object on earth to Pluto is = 100 : 9 = $\frac{100}{9}$ Weight of elephant on earth = 4100 pounds. Let weight of elephant on Pluto be $\rightarrow$ x Thus, $\frac{4100}{x}$ should be in a ratio of $\frac{100}{9}$ (Given) Thus, $\frac{4100}{x}$ = $\frac{100}{9}$ Thus x = $\frac{4100(9)}{100}$ = 41(9) = 369 So the weight of elephant on Pluto = x = 369 pounds.
