    Gemma gets 15(1/5)=3.

    Zak gets 15-3=12.

    G + Z = 15

    G : Z = 1 : 4

    G = 3

    Z = 12

    Total # shares = 4+1 = 5

    1 share = 15/5 = 3 biscuits

    Gemma gets 1 share = 3 biscuits ..............ANS

    Zak gets 4 shares = 4(3) = 12 biscuits........ANS

    Let 1k be the amount that Gemma gets

    Let 4k be the amount that Zak gets

    1k + 4k = 15

    5k = 15

    k = 15/5

    k = 3

    So:

    Gemma (1k) --> 1(3) = 3 biscuits

    Zak (4k) --> 4(3) = 12 biscuits

    think of ratio as parts

    for every 5 parts, 4 parts for Gemma and 1 part for Zak

    15 biscuits. How many sets of 5

    15/5 = 3

    calculate how many 

    3x4 for Gemma = 12

    3x1 for Zak = 3
