Answer 1

Remark

What the question is saying is that you are setting up a proportion. Ordinarily a child would require 125 mg be put into 5 mL of liquid. This child is special and only requires 100 mg. How many mL are needed?

Proportion

125 mg : 5 mL :: 100 mg: x

Solution

125 / 5 = 100 / x               Cross multiply

125x = 500                       Divide by 125

125x/125 = 500/125         Do the division

x = 4

Answer

100 mg would be put in 4 mL of liquid
