.5 is the tenth so look to the right
9 is greater than or equal to 5 so round up:
65,754.6
It's the first one (7+4i)+(7-4i)=14
As the number -1 1/2 would be to the left because it is negative, if it is as the number's integer, then the new number would be 1 1/2 because 1 1/2 and -1 1/2 are integers.
Hope this helps, if not, comment below please!!!!
