The half life of each radio-isotope is different, so there is no single answer.
84 hours
36.24 = one day.12 = half of a day.
If ' L ' is the number of days in one half-life, then the number of half-lives in 32 days is (32 / L) .
54 days is 2x27. After one cycle of a half life (27 days), one-half of the substance would be left. After a second cycle of a half life (27 more days, for a total of 54), one-half of one-half is left, or one-fourth.
The time it takes for half of the radioactive sample to decay is called the half-life. If you know the half-life of the isotope, you can calculate how long it takes for three fourths of the sample to decay by multiplying the half-life by ln(4)/ln(2).

one and a half days
Oh, dude, one and a half days is like 36 hours. Yeah, I know, it's like a whole day plus half of another one. So, if you ever need to know how many hours are in one and a half days, just remember it's 36 hours.
To determine the half-life of the substance, you can use the fact that after one half-life, the substance will be reduced to half of its original amount. In this case, after 40 days, the substance is reduced to one sixteenth of its original amount, which represents 4 half-lives (since 1/2^4 = 1/16). Thus, each half-life of this substance is 10 days.
The half-life of radon-222 is about 3.8 days. This means that it takes about 3.8 days for half of a sample of radon-222 atoms to decay into other particles.

The answer is 2. If after one half-life only half of the element remains, then after another half-life half of what was there only remains. So a half of a half is a quarter (or a fourth). So that's 2 half-lives.
