    grain 1/15 = 4 mg (1/15 X 60 = 4)
    grain 0.1 = 6 mg (0.1 x 60 = 6)

    order: 4 mg
    available: 6 mg

    Divide 4 by 6 = 0.66
    Next you need to multiply 0.66 times the quantity and that piece is missing in the info you gave. Assuming it is 1 mL 0.66 X 1 = 0.66
    The answer would be 0.66 mL or 0.7 mL if you are suppose to round to the nearest tenths place.
