You start with 5 grams- every 8 days, half of what is there goes away. At 8 days. there will be 2.5 grams. At 16 days, half of THAT is gone- now down to 1.25 grams. At 24 days, half of THAT is gone, leaving 0.625 grams. At 32 days, you have half of 0.625 grams. so divide .625 by two and you get .3125.

A 100 gram sample of a radioactive element is present at 9 a.m. on Monday and only 25 grams of the element can be detected at 9 a.m. on Friday. What is the half-life of the source?
The half-life is 2 days. You start with 100 grams. In one half life, you will lose 50 grams and have 50 grams remaining. In a second half-life, you will lose 25 of the 50 grams and have 25 grams left. You will have lost 75 grams of a 100 gram sample of radioactive material and have only 25 grams of it left after two half-lives. That means there are two half-lives from 9 a.m. Monday to 9 a.m. Friday. That's 4 days for 2 half-lives, or 2 days for one half-life.
