Answers:
earth : neptune
5 : 7
weight = 150 pounds(on earth)

1 part=150/5(5 is the ratio on earth)
1 part=30

on neptune its 7
so 7*30 =210 pounds
you are right
A person's weight on Neptune is 7/5 of their weight on earth. Multiply their weight on earth by 7, and divide the result by 5.

5/7=150/X
5X=7*150
5X=1050
X=210

But since they can't breathe on Neptune, they won't last long enough to weigh in.
