Question

pls find the sum of these question pls

Answer 1

$\frac{ - 6}{7} + \frac{ - 15}{7} + \frac{ - 15}{18} + \frac{ - 8}{18}$

$= - 3 - \frac{23}{18}$

$= - \frac{77}{18}$

Answer 2

-6/7 + -5/6 + -4/9 + -15/7

[(-108) + (-105) + (-56) + (-270)] /126

(-108 - 105 - 56 - 270) / 126

-539 / 126 = -77/18
