1) Let X = Number of oranges\r
\n" ); document.write( "\n" ); document.write( " 1.44/12 = .12 per orange\r
\n" ); document.write( "\n" ); document.write( " 4/5X (.6/4) + 1/5X (.25/2) - .12X = 5
\n" ); document.write( " 2.4X/20 + .25X/10 -.12X = 5
\n" ); document.write( " .12X + .025X - .12X = 5
\n" ); document.write( " .025X = 5
\n" ); document.write( " X = 200 \r
\n" ); document.write( "\n" ); document.write( "3) Ratio 15:6:4
\n" ); document.write( "15+6+4 = 25
\n" ); document.write( "15000/25 = 600
\n" ); document.write( "15*600 = 9000 (5c stamps)
\n" ); document.write( "6*600 = 3600 (6c stamps)
\n" ); document.write( "9000 - 3600 = 5400 \n" ); document.write( "
