Question 1137462: Hi guys, I am struggling to set this up and solving it. Can someone please help me? I am an English smartie and these word problems are a real thorn. Thank you.
The weight M of an object on the moon varies directly as its weight E on earth. A person who weighs 149.35 lb on earth weighs 25.39 lb on the moon. How much would a
251.76-lb person weigh on the​ moon?

The easiest way to do it is to use proportion


    body_1%5BM%5D%2Fbody_1%5BE%5D} = body_2%5BM%5D%2Fbody_2%5BE%5D,


where indexes / (subscripts) M and E  mean the Moon  and  the Earth, respectively.


Substitute the values


    25.39%2F149.35 = x%2F251.76


From the proportion, express 


    x = %2825.39%2A251.76%29%2F149.35


and calculate it on your own by any way.
