wait.....A and B are correct

Yeah, thats what I thought at first if I should choose D. & Can you please explain? @kelliegirl33

anonymous · Answer

you can work them out and see....
18/4 = 100/w (cross multiply)
18w = 400
w = 22.22

4/18 = w/100 (cross multiply)
18w = 400
w = 22.22

what you have to make sure of, is that whatever you put on the numerator of one, you put on the numerator of the other....same goes for the denominators...
lbs on earth/lbs on namar....earth lbs on top (numerator), lbs on namar on bottom (denominator). Now if you put lbs on namar on top, you have to put lbs of namar on the numerator of the other one  also. They have to line up.
Does that make sense ?
