Answer:
1 
Step-by-step explanation:
There are a total of 2 friends, if they have 3 cereal bars and want to split it equally then we simply need to divide the number of cereal bars by the number of friends which would give us the number of cereal bars that each individual will get, which will be represented by x
x = 3 / 2
x = 1 
Finally, we can see that each friend will get a total of 1 and a half of a cereal bar.
