$\frac{563}{120}$

Explicación paso a paso:

$\frac{3}{5} * \frac{5}{8} * \frac{7}{9} +\frac{1}{3} \div \frac{5}{21} +3\\\\\frac{3*5*7}{5*8*9} +\frac{1}{3} \div \frac{5}{21} +3\\\\\frac{105}{360}+\frac{1}{3} *\frac{21}{5} +3\\\\\frac{105}{360} +\frac{21}{15}+3\\\\\frac{105+21*24+3*360}{360} \\\\\frac{1689}{360}\\\\\frac{1689/3}{360/3} \\\\\frac{563}{120}$
