Re^2: mutliplying each element of a list by the same number

[pc88mxer]

This is just slightly more efficient (at least in terms of keystrokes if not execution time):

for (@ratio_list) { $_ *= 10 }

If you wanted to simultaneously create @minutes_list, you can use:

for (@ratio_list) { ($_ *= 10) && push(@minutes_list, $_) }

[chromatic]

for (@ratio_list) { $_ *= 10 }

If you're going to do that, why not get rid of useless punctuation altogether?

$_ *= 10 for @ratio_list;
