Question

помогите срочно пожалуйстааа​

Answer 1

P = a + b + c

$P=6\frac{4}{15}\\\\a=3\frac{1}{15}\\\\b=2\frac{7}{15}\\\\6\frac{4}{15}=3\frac{1}{15}+2\frac{7}{15}+c\\\\\frac{94}{15}= \frac{46}{15}+\frac{37}{15}+c\\\\c= \frac{94}{15}-\frac{46}{15}-\frac{37}{15} \\\\c=\frac{48}{15}-\frac{37}{15}\\\\c= \frac{11}{15}$
