lb equals 1 : 110 kg

    9.091 mg/mL means, the solution contains 9.091 mg of drug in each 1 mL. In order to express the ratio strength, we must keep the numerator in gram unit, also, the numerator should be equal to 1.
    Since 1000 mg equals 1 g, we can write 9.091 mg as 0.009 g. Thus, for this solution, we can write:
    `(0.009091\quad g)/(1\quad mL)=((0.009091/0.009091) \quad g)/((1/0.009091) \quad mL)`
    `=(1\quad g)/(110\quad mL)`.
    This is equivalent to 1 : 110. Answer.
