    Answer:

    a) 36

    b) 11:5

    Step-by-step explanation;

    a) let the number of cold stone cones be x

    Since the initial ratio is 11:9

    we have the ratio of the ice creams as;

    11:9 = 44:x

    11/9 = 44/x

    11 * x = 9 * 44

    x = (9 * 44)/11

    x = 9 * 4 = 36

    b) Now, from 36, we have a number of cold stones as 20

    So the ratio now will be;

    44:20

    and that would be;

    11:5
