<span>The ratio of an object's weight on Earth to its weight on Neptune is 5 : 7 So, We can use proportions to find out the weight of a person on Neptune. Lets start: E refers to Earth N refers to Neptune
Therefore, E:N = 5:7 Converting them into fractions: E/N = 5/7 Substituting the value of weight on earth. 150/N = 5/7 Solving for N. 5 N = 150 x 7 5 N = 1050 N = 1050/5 N = 210 pounds.
Hence,the right answer is option : </span><span>C) 210 pounds.</span>
