Answer:
1
Step-by-step explanation:
These number can be de composed in primer factors as it is shown:
100=5*5*2*2*1
5=5*1
4=2*2*1
1=1
Where we can see that the only common number is 1
-8 + 6 = - 2
So the answer is - 2
1/2 + 8 is equivalent to 1/2 - (-8)
0.5 - (-8) is ALSO equivalent to 1/2 - (-8)
0.5 + 8 is another equation that is equivalent to 1/2 - (-8)
