    The thing to do is to recognise that the full membership represents 360 degrees of the pie.

    So the proportion of Juniors members is 45/360 = 1/8

    Now you are told the total number of members in 2000 was 800. So the number of junior members is

    1/8 * 800 = 100.

    Hope this helps.
