Advanced Math practice question

Answer: 1/8 or 0.125

24 days is 3 half-lives, so the amount is halved three times: (1/2)³ = 1/8.

Common wrong answers

If you answered 1/3

1/3 divides by the number of half-lives instead of halving three times.

If you answered 1/6

1/6 halves 1/3.

If you answered 1/16

1/16 uses four half-lives (32 days).
