Buffy123 $\frac{15}{105} + \frac{21}{105} + \frac{35}{105} = \frac{71}{105} 
$
$\frac{21}{30} + \frac{4}{30} + \frac{11}{30} = \frac{36}{30}$
$( \frac{22}{33} + \frac{27}{33} )*22 = \frac{49}{33} * 22 = \frac{49*22}{33} = \frac{98}{3}$
$\frac{3}{5} : ( \frac{9}{10} - \frac{8}{15}) = \frac{3}{5} : \frac{27-16}{30} = \frac{3}{5} * \frac{30}{11} = \frac{18}{11}$
