\n" ); document.write( "\n" ); document.write( "0.35 x = ? if \r
\n" ); document.write( "\n" ); document.write( "12 = 0.15x\r
\n" ); document.write( "\n" ); document.write( "Let us solve this first: 12 = 0.15x ==> x = 80\r
\n" ); document.write( "\n" ); document.write( "So 0.35 x = (0.35)(80) = 28\r
\n" ); document.write( "\n" ); document.write( "Answer: The number is 28
