    A complete load of concrete = 8 parts gravel + 7 parts water + 5 parts cement.

    Total number of parts in every load = 8 + 7 + 5 = 20 parts

    If total load = 220 kg, then 20 parts = 220 kg

    Divide each side by 20 : 1 part = 11 kg

    gravel = 8 parts = 8 x 11 kg = 88 kg

    water = 7 parts = 7 x 11 kg = 77 kg

    cement = 5 parts = 5 x 11 kg = 55 kg

    Check: 88 + 77 + 55 = 220 yay!
