Odd prime numbers between 1 and 30 => 3, 5, 7, 11, 13, 17, 19, 23, and 29
So, there are 9 odd prime numbers between 1 and 30.
Odd prime numbers that can divide 7700 completely can be gotten from the prime factors of 7700 which is $$2^2\cdot5^2\cdot7\cdot11.$$
$$The\ odd\ ones\ are\ 5^2\cdot7\cdot11.$$
So, that means there are 3 odd prime numbers that divide 7700 completely, and they are 5, 7, and 77.
Hence, out of the total odd prime numbers between 1 and 3, the % that can divide 7700 completely will be
$$\frac{3}{9}\cdot100=33.33\%$$
