Answer 2

Answer:

-25/77

Step-by-step explanation:

to get the answer you'll need to to take:

-8/11- -9/7

so the first thing you do since you can clearly see that the denominators are different you'll need to change them by finding the lowest common multiple of each ( 11 and 7)

LCM= 77

so it would be 8x11 and 7x11 to equal 88/77

and 9x7 and 11x7 to equal 63/77

-88/77- -63/77= -88+63/77

=-25/77

so: -25/77+-8/11= -1 4/77

change to improper fraction:

(1x77)+4= 81/77

9 goes into 81= 9 times

11 goes into 77= 7 times

simplified it becomes:

9/7
