Draw out a model with 9 units.
Alvin's share of cookies = 2/3 = 6/9
Theodore's share of cookies = 2/3 of the remaining. Hence, 2/3 x 1/3 = 2/9
The last unshaded box will represent Simon cookies = 2
Since 1 unit = 2 cookies,
Number of cookies Alvin have (6 units) = (6x2) + 5 cookies =17 cookies.
Hope this helps
