200 years.
That would be 400. Because 50% is half. So 800 divided in half is 400.
82 and one half percent of 400 = 33082 1/2 % of 400= 82.5% * 400= 0.825 * 400= 330

400 years
50. First you have to find out what a quarter of 400 is before you can take half of that number. So one quarter of 400 is the same as dividing by 4, so the answer is 100. Then you'll need to take half of that number, which is 50.
For about 400 years.
It is 200
The fossil would be approximately 600 years old. We can calculate this by determining how many half-lives have passed based on the remaining 25% of the original radioactive material. Since the half-life is 200 years, and with 25% remaining, it means two half-lives have passed (50% after first, 25% after second). Therefore, 2 x 200 = 400 years.
400 + (6.5%) = 426
Well, isn't that a happy little question! If we have 800 and we want to find half of it, we simply divide it by 2. So, half of 800 is 400. Just like that, we've created a beautiful division of numbers.
There are 100 years in a century. Therefore, 400 years is equal to 400/100 = 4 centuries.
5 800 (half) = 400 400 (quater) = 100 100 (tenth) = 10 10 (half) = 5 800 / 2 = 400 / 4 = 100 / 10 = 10 / 2 = 5 :D DannyG
