Answer:
Negative, Positive, Negative, Positive
Step-by-step explanation:
1. 18.75 + (-19)
Adding a negative is the same as subtracting. 18.75 - 19 is -0.25 so the first answer is negative.
2. +
If you convert the fraction in the second term to one with the same denominator (three and 8 10ths), you can see that since 8 tenths is more than 7 tenths, the equation will result in positive 1/10
3. 9.4 + (-)
3/5 is the same as 6/10 or .60
9.6 is more than 9.4, so the negative is further from zero than the positive.
4. -7 + 7 + 1/2
-7 + 7 is zero. zero + 1/2 is positive 1/2
