Answer :

Answer: 107.14

Step-by-step explanation:

Given that the weight ratio of an object on Earth to Neptune is 5:7, we can set up a proportion to find the weight of a person on Neptune.

Let's denote the weight of the person on Earth as x pounds.

The ratio of weight on Earth to weight on Neptune is 5:7, which can be represented as:

x/150=5/7

Cross multiplying, we get:

$7x = 5 \times 1507x=750

Dividing by 7 to solve for x:

x=750/7

x=107.14

Therefore, a person who weighs 150 pounds on Earth would weigh approximately 107.14 pounds on Neptune.
