When you are doing dilutions the larger number is always the total final volume. The smaller number is the amount of the solute. The larger number minus the smaller number is the amount of the solvent. So a 1:5 or a 1 IN 5 dilution would be 1 part solute and 4 parts solvent to come to a total volume of 5.
When referencing ratios in mathematics 1:5 means 1 TO 5. The ratio is relative to the two items. For every 1 of the first you have 5 of the second.
It is critical if you are making dilutions to understand the difference as the two explanations are not interchangeable.

The geometric mean of 10 and 12 is: 10.9544511501
The geometric mean of 10 and 20 is 14.1421356237
1/10 + 1/10 = 2/10 = 1/5.
MEAN = ( 8+10 )/2 = 18/2 =9
It is a mixture of 1 part of the active ingredient (by volume) to 10 parts of the solvent.
Add 2 mL of culture to 20 mL of buffer. 2/20 = 1/10
Means that there is no dilution.
1 in 25. (10/250)
dilution rate RTU
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.
take 1 ml, add 9 ml water.
10
By 10-fold dilution
10
An 8-fold dilution means you are making your solution 1/8 less concentrated. So, if you want to make 100 ml of a solution diluted 8 fold you would do as follows: 1/8=.125 100*.125= 12.5 Mix 12.5 mL of your concentrated solution with 87.5 mL of your solvent (water etc..) to bring the final volume to 100 mL. If you wanted to perform a ten fold dilution you would simply mix 10 mL of your concentrated solution with 90 mL of your solvent. 1/10=.1 100*.1=10
You add 9.09ml of stock solution to a volumetric and make it up to 1 litre to get a 110 dilution
