Answer 1

$( - \frac{34}{57} ) + ( \frac{51}{79} ) + ( - \frac{51}{12} )$

$= - \frac{ 2.686}{4.503} + \frac{2.907}{4.503} - \frac{51}{12}$

$= \frac{ - 2.686 + 2.907}{4.503} - \frac{51}{12}$

$= \frac{221}{4.503} - \frac{51}{12}$

$= \frac{221}{4.503} - \frac{17}{4}$

$= \frac{884}{18.012} - \frac{76.551}{18.012}$

$= \frac{884 - 76.551}{18.012}$

$= - \frac{75.667}{18.012}$

$= - 4.20$
