#### Answer

Weight of elephant on Pluto = 369 pounds

#### Work Step by Step

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.
