    Answer:

    368 milliliters.

    Step-by-step explanation:

    Compound A + Compound B = 1 drug

    4 + 7 = 1 drug

    11 milliliters = 1 drug, so 1012 milliliters = 92 drugs

    Multiply the compounds by the amount of drugs, e.g.

    4 x 92 = 368 ( Compound A )

    7 x 92 = 644 ( Compound B )

    368 + 644 = 1012

    368 milliliters of Compound A are needed to make 1012 milliliters of the drug.

    Hope this helps 🙂
