Question 1187931


{{{p}}} is jointly proportional to {{{q}}} and {{{r}}} 

{{{p=k*qr}}}  where {{{k }}}is constant

{{{k=p/(qr)  }}}

if {{{p = 12 }}}when {{{q = 8 }}}and {{{r = 3}}}, than

{{{k=12/(8*3)}}}
  
{{{k=12/24}}}  

{{{k=1/2}}} 

and equation is

{{{p=(1/2)qr }}}


Constant: {{{1/2}}} 

Equation:{{{p=(1/2)qr }}}
