5 percent of 20 million dollars is 1 million dollars
1 million × 4000 = 1000000 × 4000 = 4000000000 = 4 x 10^9 * In those countries which use the long scale (based on powers of a million) eg Europe: 4 × 10^9 = 4000 x 10^6 = 4 thousand million or 4 milliard * In those countries which use the short scale (based on powers of a thousand plus one) eg USA: 4 x 10^9 = 4 billion.
.01 x 40 million = 400,000 dollars

4000 million.
4,000,000 (four million) milicuries
5 percent of 20 million dollars is 1 million dollars
1 million × 4000 = 1000000 × 4000 = 4000000000 = 4 x 10^9 * In those countries which use the long scale (based on powers of a million) eg Europe: 4 × 10^9 = 4000 x 10^6 = 4 thousand million or 4 milliard * In those countries which use the short scale (based on powers of a thousand plus one) eg USA: 4 x 10^9 = 4 billion.
.01 x 40 million = 400,000 dollars
4000 × 500 = 2,000,000 Two million.
1% of 4000 = 40= 1% * 4000= 0.01 * 4000= 40
To calculate 250 ppm (parts per million) chlorine solution in water, you would need 250 parts of chlorine for every 1 million parts of water. This can be simplified to 1 part of chlorine for every 4000 parts of water (since 1 million divided by 250 is 4000). Therefore, you would mix 1 unit of chlorine with 4000 units of water to achieve a 250 ppm chlorine solution.
