Question

-9/42+(-5/21)+3/84+1/6​

Answer 1

Step-by-step explanation:

$\frac{ - 9}{42} + \frac{ - 5}{21} + \frac{3}{84} + \frac{1}{6} \\ = \frac{ - 18 + ( - 20) + 3 + 14}{84} \\ = \frac{ - 18 - 20 + 3 + 14}{84} \\ = \frac{ \cancel{ - 21} _{ \: \: - 1} }{ \cancel{ 84} _{ \: \: 4} } \\ \boxed{= \underline{ \underline{ \frac{ - 1}{4} }}}$
