It is a mixture of 1 part of the active ingredient (by volume) to 10 parts of the solvent.
To make an 8-fold dilution, you would mix 1 part of the substance you want to dilute with 7 parts of the diluent (usually water or buffer solution). This results in a total of 8 parts, with 1 part being the original substance and 7 parts being the diluent. This dilution reduces the concentration of the original substance by a factor of 8.
Assuming you mean 10/20, (10/20)/(4-5)=0.5/-1=-1/2 Assuming you mean 10.20, 10.2/-1=-10.2 Assuming you mean 10-20, (10-20)/(-1)=(-10)/-1=10
To make a 1 to 5 dilution you mix 1 part of your substance with 4 parts water. ie: Mix 1 tablespoon of creamer with 4 tables spoons of coffee, and the coffee is 1/5 creamer now.
1X PBS might mean 1 in 10 solution 1/10

Add 2 mL of culture to 20 mL of buffer. 2/20 = 1/10
1 in 25. (10/250)
To dilute a 10 ppm solution to 1 ppm, you would mix 1 part of the 10 ppm solution with 9 parts of a diluent (such as water). This would result in a 1 ppm concentration because the concentration has been decreased by a factor of 10 during the dilution process.
take 1 ml, add 9 ml water.
In chemistry and biology, the dilution factor is the total number of unit volumes in which the material is dissolved. As I understand it, the dilution refers to the dilution ratio. If you add 1 part of something to 4 parts of something else, the dilution ratio is 1 to 4. The dilution factor counts all the parts and expresses the same thing as 1 out of 5.
0 percent dilution means that no additional solvent or liquid has been added to a solution. The solution remains in its original concentration without any dilution.
A 1 in 50 dilution means that one part of a substance is mixed with 49 parts of a diluent, resulting in a total of 50 parts. This is often expressed as a ratio (1:50) or as a fraction (1/50), indicating that the original substance is present at a concentration of 2% (1 part out of 50). This type of dilution is commonly used in laboratories for preparing solutions with specific concentrations.

In a typical milk dilution experiment, milk can be diluted with water in ratios such as 1:1, 1:2, or 1:10. These dilutions are used to reduce the concentration of milk proteins, fats, and sugars in order to study the effects of dilution on various properties of milk, such as color, taste, and viscosity. The dilution ratio chosen will depend on the specific research question being addressed in the experiment.

To make a 1 to 1 dilution, you combine equal volumes of the concentrated solution and a diluent, typically a solvent like water. For example, if you have 10 mL of the concentrated solution, you would add 10 mL of the diluent. Mix thoroughly to ensure a uniform solution. This results in a final volume of 20 mL at half the concentration of the original solution.
1:2 means "1 part to 2 parts", so if the "1 part" is what you are diluting, it is actually a 1/3 dilution (one part into 3 parts total). On the other hand, 1/2 means "1 part into 2 parts total", and in the colon nomenclature that would be a 1:1 dilution.
