for every 250000, there is 50% left from original mass

10000/250000=.04 of what?

There is an equation, but over here its night time and my brain is turned off, so i did it algebraicly

Even more importantly, do not post incorrect solutions. The algebraic approach is approximately correct.

amanaka, do you know what the relevant equations are for radioactive decay?
