**bonjo**, Sunday, May 12, 2013 at 7:48pmfraction remain = (1/2)^n where n is the number of half life

half life = p/n where p is the period of decaying i.e. 47 years

so, first find n (number of half life using the half life equation and then find the fraction remain. convert this fraction to %

hope that helps
