Thank you for the opportunity to help you with your question!

1. -91 +7 = -84

2. 36 +(-9) = 36-9= 45

3.-54+(-9) = -54-9= -63

4. 75+15 =90

5. 0+(-7) = 0-7 = -7

6. 56/-7 = -8

7.-72/-12 = 72/12 = 6

8.102/-17 =-6

13. 24 +(-12) = 24-12 = 12

14. -144 +3 = -141

15.0/-4.12 = 0

16. 1/8+-6/5 = 1/8 -6/5 = 5/40-48/40 = -43/40

17.-3/7 +-8/ 21  =-(3/7 +8/21) = -(6/21+8/21) = -14/21 = -2/3

18. -10 +1/3 = -9 and 2/3

19-3/4 +(-12) = -(3/4+12) = - 12 and 3/4

20 -15 +3/5 = -14 and 2/5


Please let me know if you need any clarification. I'm always happy to answer your questions.

Since it is partly your fault I will only assist if you promise to be asking me questions directly

Technique

positive no / negative number = negative number

positive number / positive number = positive number

negative number/ negative number = positive number

zero divided by any number = zero

2. 36 /(-9) = -4

3.-54/(-9) = 6

4. 75/15 = 5

5. 0/(-7) = 0

6. 56/-7 = -8

7.-72/-12 = 6

8.102/-17 =-6

13. 24 /(-12) = -2

14. -144 /3 =  -48

15.0/-4.12 = 0

16. 1/8/-6/5 = 1/8 *-5/6 = -5/48

17.-3/7 /-8/ 21  =-3/7 * -21/8 =9/8

18. -10 /(1/3) =-10 *3 = -30

19 -3/4 /(-12) = -(3/4*1/12) = 1/16

20 -15 /3/5 = -15*5/3 = -25
