I'm having a hard time with this problem, please, help me?

b) How long would it take the sample to decay to 20% of its original amount?

2) A sample of ³H, the hydrogen isotope known as "tritium," decays to 94.5% of its
original amount after a year (that is, 5.5% of it decayed in one year). You should use a calculator on
this question.
a) What is the half-life of tritium (that is, the time expected for half of the original sample
to decay)?
