A box contains 3 dumb-bells.
Each dumb-bell has a mass of 

   3

3 --

   5

 kilograms.
What is the mass of 2 similar boxes?
(Leave your answer as a mixed number in simplest form.)

Each dumbell   weighs   3 3/5 kg

 

3  3/5   kg/dumb   x 3  dumb    =  18/3  x 3  =  54/3 =   18 kg       (the amount EACH BOX weighs)

 

2 boxes  x  18 kg/box =   36 kg      for 2 boxes
