64Cu(T50=12.8h) decays β- emission( 38 %),β+ emission(19%) and electron capture(43%).Write the decay products and calculate partial half-lives for each of the decay process.
didnt exactly understand the q.

T1/2 of Cu=12.8hr
let k1,k2,k3 be the decay constants for the 3 processes.
Total K =0.7/12.8=5.4\times 10^{-2}
K1,k2,k3 r proportional to their respective percentages....
k1=0.38K
K2=0.19k
K3=0.43k
