#244.4#.

Explanation:

Mental math:

Calculate #1%# of #260="   "2.6#

So #6%# of #260=6timescolor(blue)"2."color(magenta)6#
#"                       "=(6timescolor(blue)2)+(6timescolor(magenta)0.6)#
#"                       "=12+3.6#
#"                       "=15.6#

Then #94%# of #260# is the whole #260#, minus #6%# of it:

#94%times260=260-(6%times260)#
#"                    "=260-15.6#
#"                    "=244.4#

All without the need for a calculator!
