    (a) a : b = 11 : 3

    (b) a : b : c = 22 : 6 : 3

    Step-by-step explanation:

    (a) Dividing the given equation by 3b, we get ...

    (3a) / (3b) = (11b) / (3b)

    a/b = 11/3

    a : b = 11 : 3

    __

    (b) We are given b = 2c, so c = b/2. Then we have the ratio ...

    a : b : c = 11 : 3 : 3/2

    We can clear the fraction by multiplying by 2:

    a : b : c = 22 : 6 : 3
