Reduction of photographs from the 180-liter xenon bubble chamber yielded 2768 and 5190 events of K/sup +/..-->..e/sup +/..pi../sup 0/..nu.. and K/sup +/..--> pi../sup +/..pi../sup +/..pi../sup -/ decays, respectively. A ratio GAMMA(K/sup +/..-->..e/sup +/..pi../sup 0/..nu..)/GAMMA(K/sup +/..--> pi../sup +/..pi../sup +/..pi../sup -/) = 0.867 +- 0.027 was obtained.
