Give an example (or two) of single dilution steps that would be
For simplicity, make the dilutions powers of 10 (that is 10, 100,
etc). That isn't always done, but it is easier, and there is no reason
here to make it more complex.
Have you done any microbiology lab work? If so, you should have
encountered some common dilutions. If not, invent one or two that fit
the rules given in the problem. (There are many ways to solve the
problem, so it is for you to be bold and do it.)
