    5:2 is the same as 15:6

    2 for me, 5 for you. 2 for me, 5 for you. 2 for me, 5 for you.
    6 for me, 15 for you.

    3:1 is the same as 6:2

    Therefore a:b is 15:6 and b:c is 6:2 so what is a:b:c ?

    Yes, that is correct.

    All you need to do to get these ratios is to make the letter in common have the same value. For the first problem, b was the letter in common so you make make that letter have the same value without altering the ratios.
