#2#.

Explanation:

To start, convert #3/5# to a decimal:

#3/5=0.6#

We'll set up an equation, which says that #3/5# (#0.6#) is #30%# (#0.3#) times a number:

#0.6=0.3x#

Divide both sides by #0.3#:

#0.6/0.3=(0.3x)/0.3#

#0.6/0.3=(color(red)(cancel(0.3))x)/color(red)(cancel(0.3))#

#0.6/0.3=x#

#2=x#
