Question

A half-life is a "tick" of the clock. If you know what percentage of the original material is left, you can determine how many times the clock has ticked. Convert these percentages into half-lives.

The half life is 348,333,333, from an original starting value of 696,666,666

25%

12.5%

6.25%

I am so lost. I have tried to solve this for days. I have tried evrything, but when I get the wrong answer, it says "That's not correct. You should be able to see a pattern here. If you can't, divide 100% by two, and the results by two, to see if you can replicate this pattern."

Explanation / Answer

Answer:

As it is given that 1 tick represents 1 half life of element, and the parent life is 696,666,666 and half live is 348,333,333 which means 50% and clock ticks once to get this half live.Therefore, if we follow the same pattern we get 174166666.5 for 25%(clock ticks twice), 87083333.25 for 12.5% (clock ticks thrice) and 43541666.625 for 6.25%(clock ticks four times).
