T years=1/3.

Thus

1/2 T years=1/6.

Thus 3/2 T years is a half life.

I think that’s right.

1/3=2/6.

1/6= 1/2*1/3…

yeah.

1.5 T years

if T = 1/3, then 3T is the time it takes for all of it to disintegrate… the halflife is the time it takes for half of it to disintegrate, so 1/2 of 3T = (3/2)T or 1.5T
