5.9, you have to cross multiply to find the answer. Look at khan academy's lesson :)

Divide the astronauts on Jupiter weight by the earth weight to get the difference between the two: 445/175=2.54. Divide the dogs on Jupiter weight by the difference between the two: 114/2.54=44.9.
The dog weighs 44.9 pounds on earth.
Divide the astronauts on Jupiter weight by the Europa weight: 445/23=19.35. Divide the dogs on Jupiter weight: 114/19.35=5.9.
The dog would weigh 5.9 pounds on Europa :)
