The easiest "trick" to scale numbers in this way is to first scale them to
the range 0-1 and then scale them to the desired range.

  So if you have numbers between 0.1 and 1, you first scale them to be
between 0 and 1: normalized=(number-0.1)/(1-0.1)

  Now you scale this to the range 0.6-1: normalized*(1-0.6)+0.6

  If we write that into one line, it would be:

  (number-0.1)*(1-0.6)/(1-0.1) + 0.6

and simplifying a bit:

  (number-0.1)*0.4/0.9 + 0.6
