Sarin, Hairu and Fatimah have some stickers. Sarin has thrice as many stickers as Hairu. Fatimah has 4 times as many stickers as Sarin. What is the ratio of the number of stickers Hairu has to the number of stickers Fatimah has?

                        Sarin’s sticker : Hairu’s stickers : Fatimah’s stickers = 3 : 1 : 12

                        The ratio of the number of stickers Hairu has to the number of stickers Fatimah has = 1 : 12

Alternative solution:
