Answer 2

1) $16 \frac{1}{5} - 1 \frac{14}{15} = \frac{81}{5} - \frac{29}{15} = \frac{243}{15} - \frac{29}{15} = \frac{214}{15}$

$\frac{12}{7} + \frac{81}{21} = \frac{36+81}{21} = \frac{117}{21}$

$\frac{214}{15} : \frac{117}{21} = \frac{214}{15} * \frac{21}{117} = \frac{214}{5} + \frac{7}{117} = \frac{25073}{585}$
