\n" ); document.write( "x = some positive real number
\n" ); document.write( "x > 0\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The ratio 7:6:2 scales up to 7x:6x:2x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7x = weight of strawberries
\n" ); document.write( "6x = weight of grapes
\n" ); document.write( "2x = weight of blackberries\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Their sum is 5 pounds total
\n" ); document.write( "7x+6x+2x = 5
\n" ); document.write( "15x = 5
\n" ); document.write( "x = 5/15
\n" ); document.write( "x = 1/3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore,
\n" ); document.write( "7x = 7*(1/3) = 7/3 = 2 & 1/3
\n" ); document.write( "6x = 6*(1/3) = 2
\n" ); document.write( "2x = 2*(1/3) = 2/3\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: 2 & 1/3 pounds of strawberries.
\n" ); document.write( "Equivalent to 7/3 pounds or roughly 2.333 pounds.
\n" ); document.write( " \n" ); document.write( "
