lb equals 1 : 240 kg

    4.167 mg/mL means, the solution contains 4.167 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 4.167 mg as 0.004 g. Thus, for this solution, we can write:
    `(0.004167\quad g)/(1\quad mL)=((0.004167/0.004167) \quad g)/((1/0.004167) \quad mL)`
    `=(1\quad g)/(240\quad mL)`.
    This is equivalent to 1 : 240. Answer.
