The ratio of an objects weight on earth to its weight on Neptune is 5:7. How much would a person who weighs 150 pounds on earth weigh on Neptune? A.210 pounds B.750 pounds c.107 1/7 pounds D.170 pounds

5/7 = 150/x

Cross multiply and solve for x.

To find out the weight of a person on Neptune, given their weight on Earth and the ratio, follow these steps:

Step 1: Set up the ratio:
The ratio is given as 5:7, which means the Earth weight is the first number (5) and the Neptune weight is the second number (7).

Step 2: Determine the weight on Neptune:
We'll assume the weight on Earth is 150 pounds. To find the weight on Neptune, we'll set up the proportion:

Earth weight / Neptune weight = Earth-to-Neptune ratio

150 pounds / Neptune weight = 5 / 7

Now, we can cross-multiply:

5 * Neptune weight = 7 * 150 pounds

Step 3: Solve for Neptune weight:
Divide both sides by 5:

Neptune weight = (7 * 150 pounds) / 5

Neptune weight = 1050 pounds / 5

Neptune weight = 210 pounds

Therefore, a person who weighs 150 pounds on Earth would weigh 210 pounds on Neptune.

The correct answer is A. 210 pounds.
