lbs are an old unit and I suspect the question is using them to see if you are clear in your mind as to the difference between mass and weight. lbs are awkward because they are used for both mass and weight: the 1 lb weight = 1 lb mass conversion works on Earth because the acceleration on Earth is 1 gravity [or 1 "gee"]
How much does a person who weighs 180lb on earth weigh on the Moon?
so same mass but less weight on the Moon. How about on a moon a little smaller than ours where the acceleration due to that moon's gravity is 0.9m/sec/sec [please start giving answers with appropriate units as the correct selection of units is at the heart of the problem]
(I'm ignoring that 1/6 less is not the same as 1/6th)
it is straightforward. but only once you can see the difference between mass and weight. You should then be able to see if the units in the problem are consistent or if some conversion is necessary.
For myself I kept the lbs weight and converted acceleration into earth gravities aka "gee"s The numbers in the question look a lot like what I might see if I took my bathroom scales into a lift and selected to go up or maybe down.
