Microbiologists please help

Hi so my question is basically on dilutions which I need to do for carrying out an MIC test in microbiology

 

a 1 in 10 dilution converted to percentage is 0.01, a 1 in 100 dilution is 0.001, however if I had a 1 in 10 dilution in my microtitre plate well A1 in which I have added 1ml of bacteria and 9ml of water, how much would I be taking from this first well to the second well to make it 0.06% ? and how much sterile water would I be adding ?

 

and also is 0.06, a 6 in 100 dilution ?

 

please help confused !

Why is a 1 in 10 dilution 0.01?

Why is a 1 in 10 dilution 0.01?

because 1/100 is 0.01 ? am i right

because 1/100 is 0.01 ? am i right

 

That's correct, but that would be a 1:100 dilution, not 1:10.
