Answer: 50% are blue.
Step-by-step explanation:
The total number of skittles in the packet will be represented by 100%. If 27% are red and 23% are green then the combination of the red and green skittles subtracted from 100 will give the percentage of the blue skittles.
27% + 23% = 50%
100% - 50% = 50%
This means half of the skittles in the packet are blue which is 50%.
