Given that m varies directly with n
\n" ); document.write( "That is m α n
\n" ); document.write( "m = kn  (1)
\n" ); document.write( "Where k is the constant of variation.
\n" ); document.write( "Now substitute the values for m = 144 and n = 8, we get
\n" ); document.write( "144 = k*8
\n" ); document.write( "Divide the above equation by 8, we get
\n" ); document.write( "144/8 =k
\n" ); document.write( "18 = k
\n" ); document.write( "The constant of proportionality is 18.
\n" ); document.write( " \n" ); document.write( "
