(a) 2/7
(b) 2/15
(c) 1/12
(d) 7/24

The total number of candies Julie has is 15 + 7 + 2 = <<15+7+2=24>>24 candies.

The ratio of blue candies to total candies is 2/24.
To simplify this ratio, we divide the numerator and the denominator by their greatest common divisor, which is 2.
So, the simplified ratio is 1/12.
Therefore, the answer is (c) 1/12.
