If j and k are inversely proportional and j = 42 when k = 56, what is the value of j when k = 32? Express your answer as a decimal rounded to the nearest tenth.

j =  m / k              where m is the proportionality  constant

 

42 =  m /56

 

56* 42  =  m  = 2352

 

So

 

j =  2352 / 32  =  73.5
