33 = 3 * 11. The rest are prime.
81
93 = 3 x 31
They are all the numbers except 71 73 79 83 89 and 97 which are prime numbers
13, 23, 43, 53, 73, and 83
A prime number has exactly two factors, 1 and the number itself. 33 obviously has more factors because it is a multiple of 3 and 11, so it is not a prime.

93 = 3 x 31
All except 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101 and 103.
The composite numbers are:2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97.

43% of 83 = 43% * 83 = 0.43 * 83 = 35.69
