cont. time signal and disc. time signal frequency??

[magneeto]

hi,

i am having some trouble understanding the relationship between continuous time signal frquency and discrete time signal frequency. if anyone is currently reading the book "digital signal processing " by proakis and manolakis please see page no 27 fig 1.17. i don't understand how this sawtooth figure came up from the relation f=F/Fs (if i am right!).
