it depends on how much each stamp is worth
280 ml of water is 280 grams
280/5 = 56
Someone's used passport will have used stamps. A stamp album will have many used stamps. And most scrapbooks have many stamps in them.
20 stamps
100
280/10 = 28
To find how many times 20 goes into 280, you can divide 280 by 20. This calculation gives you 280 ÷ 20 = 14. Therefore, 20 goes into 280 a total of 14 times.
how many forever stamps = .94
280 kilograms = 280,000,000 milligrams
in 280 metres there are 0.28 kilometers
280 meters = 11,023.622 inches.
280/9 should get you the answer.
