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.
