Answer 2

first we have to find the LCM of 9 12 18

LCM of 9 12 18 is 36

Step-by-step explanation:

in the next step we have to multiply both the rational numbers to get the denominator is 36

-16/9=. -16*4/9*4=. -64/36

-5/12= -5*3/12*3= -15/36

7/18=. 7*2/18*2=. 14/36

and the next we have to add the both

= -64/36+(-15)/36+14/36

the LCM of these three things is 36

= -64-15+14/36

= -65/36

the required answer is

-65 / 36
