Divide 117 by 3, and when you get your answer (which should be 39), multiply it by 2 and you should get 78. That's the answer to Number 4.
For number 5, 1/4 is equal to 0.25, 15% is equal to 0.15, 0.3 can stay as 0.3 (30%), and 12% is equal to 0.12. If you look at the decimal, 0.3 is equal to 30%, so cousin Timmy ate the most.
The fraction, decimal or percent equals 0.82. All you have to do is add all of the decimals together. I choose decimal because it is the easiest to do. Hope that helped
