Answers:
26/7
3 5/7
==========================================
Step-by-step explanation
There are 26 cake slices that are green (7*3 = 21 slices from the first 3, then another 5 green slices, so 21+5 = 26 green total).
Each slice represents 1/7 of a circle. That's how we get to the improper fraction 26/7.
-------
The mixed number answer is 3 & 5/7 or 3 5/7.
Whole part = 3
Fractional part = 5/7
We have 3 full cakes plus an additional 5/7 of another cake.
