Question

Find the sum of - 7/9, - 5/12 and 13/18​

Answer 1

Answer:

17/36

Step-by-step explanation:

(-7/9) + (-5/12) + (-13/18)

7/9 + 5/12 - 13/18

(7*4 + 5*3 - 13*2)/36

(28 + 15 - 26)/36

17/36

Answer 2

$= \frac{ - 7}{9} + ( \frac{ - 5}{12} ) + \frac{13}{18}$

$= \frac{ - 7}{9} - \frac{ 5}{12} + \frac{13}{18}$

$= \frac{ - 28 - 15 + 26}{36}$

$= \frac{ - 17}{36}$
