1: 80% The reason why is because if you do 4/5, you get .80, move the decimals to places to the right, and you get 80%
2: 95% Process of Elimination, and Educated Guess.
3: 33 1/3% If you do 50/150, you get 0.33333... Like I said, move the decimal point two places to the right, and you get 33.33...%

7 = 2n - 2
n= a number so twice a number is 2n and 7 is 2 less than twice this number.
Factors of 3771 are:
1, 3, 9, 419, 1257, 3771
Factors of 3298 are:
1, 2, 17, 34, 97, 194, 1649, 3298
As you can see, no factors goes into both number.
Therefore, there should be no number goes into both 3771 and 3298 evenly.
Hope this helps and hope I didn't misunderstood this question. :D
