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.

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.

A 1:2 dilution means mixing 1 part of a substance with 2 parts of solvent or diluent, resulting in a total of 3 parts. A 1/2 dilution involves dividing the original concentration in half, resulting in a 1:1 dilution ratio of the original substance.
To prepare a 10-liter solution of Roundup, you'll need to follow the manufacturer's instructions, which typically specify a dilution rate. For example, if the recommended dilution is 10 mL of Roundup per liter of water, you would need 100 mL of Roundup for a 10-liter solution. Always refer to the product label for the exact dilution ratio specific to the type of Roundup you are using.
The CDC recommends using a 1:10 dilution of bleach to water to effectively decontaminate bloodborne pathogens. This means mixing 1 part bleach with 9 parts water. Always follow the manufacturer's instructions for proper dilution and contact time for disinfection.
