A percentage measure is appropriate only when both measures are in the same units (or their multiples). Milligrams are a measure of mass while millilitres are a measure of volume. The two measure different things and they cannot be converted into a percentage.

How many milligrams of an active ingredient are needed to make 400 ml of a 1 in 1000 solution?
It is not clear whether the strength of the solution is given in terms of mass/mass or volume/volume (or mass/volume). Without that information, it is not possile to answer the question. Depending on which one you may need the density of the active ingredient or of the solvent to convert between mass and volume of that component.
How many gallons of a 60 percent antifreeze solution must be mixed with 70 gallons of 30 percent antifreeze to get a mixture that is 50 percent antifreeze?
Suppose G gallons are required. G gallons @ 60% implies 0.60*G gallons of the active ingredient. 70 gallons @ 30% implies 70*0.3 = 21 gallons of the active ingredient. This makes a total of (G + 70) gallons containing (0.6G + 21) gallons of active ingredient. The mixture is (0.6G + 21)/(G + 70) which is to be 50% or 0.5 So 0.6G + 21 = 0.5G + 35 or 0.1G = 14 which gives G = 140 gallons
How many gallons of a 60 percent antifreeze solution must be mixed with 70 gallons of 10 percent antifreeze to get a mixture that is 50 percent antifreeze?
Suppose G gallons of 60% antifreeze are required. G gallons of 60% contain 0.6G gallons of the active ingredient. 70 gallons of 10% contain 7 gallons of the active ingredient. So, in the mixture, there are G + 70 gallons containing 0.6G + 7 gallons of the active ingredient. This is to represent 50%. So 0.6G + 7 = 0.5*(G + 70) = 0.5G + 35 0.1 G = 35 - 7 = 28 G = 280 gallons.

What is an osmotically active substance?
It is a solute that causes osmosis to occur. For instance, if a solution contains sucrose and the membrane is impermeable to sucrose,, water will move out of the cell and into the solution to dilute it. Hence the solution is hypertonic. Sucrose would be considered an osmotically active solution in this case because it induces osmosis of water across a membrane.
A suspension contains 2400 mg of active drug in 1000 ml What is the percentage of drug in the final product?
Scientifically, percentages can used to describe the number of grams of substance in 100ml. In this case, there are 2.4g in 1L... which is equivalent to 0.24g in 100mL... which is the same as a 0.24% solution
