Can someone correct my Concentration/Dilution problem?

I have a solution of methyl red which is 3.27x 10^ -4 M that is prepared by diluting 10 mL to 100mL. What is the concentration?

Is doing (3.27x10^-4)(.01)= x(.1) to solve for the concentration the right way?
= 3.27x10^-5

Thanks in advance!

Your result of 3.27x10^(-5) is correct, but your equation
is incorrect. It should be : [3.27x10^(-4)](10) = x(100).

10ml to 100ml can be done in your head - it's one tenth of the concentration that it was before!

Yes, you've done it correct by using

c1xv1=c2xv2
