Answer 1

$a) = \frac{37}{30} + (0.8 - 2.13)$

$= \frac{37}{30} + ( - 1.33)$

$= \frac{37}{30} - 1.33$

$= \frac{37}{30} - \frac{133}{100}$

$= - \frac{29}{300}$

$b) \frac{63}{20} + ( \frac{3}{7} - \frac{8}{15} )$

$= \frac{63}{20} + ( - \frac{11}{105})$

$= \frac{63}{20} - \frac{11}{105}$

$= \frac{1279}{420}$
