lb equals 1 : 890 kg

    The strength 0.112 % w/v means, there is 0.112 g of drug dissolved in each 100 mL of the solution. We need to convert this to a suitable ratio which has 1 in the numerator. Therefore, `(0.112 \quad g)/(100\quad mL)=((0.112/0.112)\quad g)/(100/0.112\quad mL)=(1\quad g)/(890\quad mL)`.

    Therefore, the ratio strength is 1 : 890.
