Answer:
-3.2
Step-by-step explanation:
When adding a positive number to a negative number, you are basically subtracting. 6.3 + (-9.5) is also the same as 6.3 - 9.5.
When dealing with decimals, you can work with the decimal and whole number separately.
6 - 9 = -3
.3 - .5 = -.2
Put them together and you have -3.2
A quick little rule as well, when adding a positive to a negative, if the absolute value of the negative number is larger than the positive number, the answer will be negative. If the absolute value of the negative number is less that than the value of the positive number, the answer will be positive.
Hope this helped! :-)
