Please answer the questions before 12 am

(28) is 7 because in division two negatives make a positive

(29) it is -5 because u only have one negative so u put it in the answer

(30) it is -2 once again because u only have one negative so u put it with the answer

(31) is -9

28. -28/-4=+7 because in devision a negative denominator and dominator is positive.
29.-10/2=-5 this is because a negative number dividing a positive number is negative.
30. 12/-6=-2 because a positive dividing a negative number is also negative
31. -54/6 =-9 because a negative dividing a positive number is given as negative also

I hope this answer could help
