There are 3 people -- David, Angie, and Hank.
They have
4 granola bars
4 cereal bars
That's a total of 4 + 4 = 8 bars
Thus, 8 bars needs to be shared among 3 people.
We divide total number of bars by the total number of people to find how many each of them receive!
Thus,
[tex]\frac{8}{3}[/tex]Each person will receive 8/3rd bars.
