The ratio of an object weights on Earth to its wieght on Neptune is 5:7. HOw much would a person who wieghs 150 pounds in Earth weigh on Neptune?
(Weight on Earth)/(Weight on Neptune) = 5/7
Thus the weight on Neptune is 7/5 or 1.4 times the weight on Earth.
A better value is 1.2. They may have been using older data. For a reference on this, see

white a ratio the number 21% - 24%
To find out how much a person weighing 150 pounds on Earth would weigh on Neptune, we can use the given ratio of weights on Earth and Neptune.
The ratio of the object's weight on Earth to its weight on Neptune is 5:7. Let's assign a variable to represent the weight on Earth (W₁) and the weight on Neptune (W₂).
We know that the weight on Earth (W₁) is 150 pounds. So we can set up the proportion:
W₁ / W₂ = 5 / 7
Substituting the given values:
150 / W₂ = 5 / 7
Now, we can solve for W₂ (the weight on Neptune).
We can cross multiply:
5 * W₂ = 7 * 150
5 * W₂ = 1050
Divide both sides by 5:
W₂ = 1050 / 5
W₂ = 210
Therefore, a person weighing 150 pounds on Earth would weigh 210 pounds on Neptune.
