Since the Mongolian Meteorite weighs 22 tons and we know that the US one weights 70% or (.7) of that weight we can multiply 22 by .7 to get the weight of the United States meteorite.
15.4 Tons
the answer would be 15.4 tons 
7/10 x 22= 15 2/5 and and in decimal form it would be 15.4 hope it helps :)
