In the f(2)(1270)-f ' (2)(1525) mixing framework, the isoscalar singlet-octet mixing angle for the 1 P-3(2) tenser nonet is determined to have the value of 27.5 degrees and the decays of the two states are investigated. Comparing the predicted results of the decays of the two states with the available experimental data, we find that the predicted results based on this simple mixing picture are in good agreement with the experimental data, which show that the f(2)(1270) and f ' (2)(1525) wavefunctions do not need other components such as glueballs or the 2 P-3(2), 3 P-3(2),..., q (q) over bar.
