Answer 18

Okay, for the first question:
Two negatives make a positive, so that gets rid of half of the answer choices, Then if we do the operation, we get 3.78. So your final answer would be D.

For the second question:
First do 15/5...
15/5=3
now do 0.5/5
0.5/5=0.1
add the two values: 3+0.1 = 3.1
Dont forget that the original number was negative so our answer will be negative.
Final answer: A. -3.1

Answer 19

For the third question:
We can change the division sign to multiplication if we use the reciprocal of the second fraction.

\[\frac{ 3 }{ 5 } * -\frac{ 9 }{ 4 }\]

3*-9=-27
5*4=20
Final answer= \[-\frac{ 27 }{ 20 }\]
