#3/25#

Turn the two numbers into fractions and then multiply.

#0.4=4/10=2/5#

#0.3=3/10#

#(2/5)*(3/10)=(2*3)/(10*5)=6/50=3/25#

A different approach

#0.12#

#0.4# is the same as #4xx1/10#

#0.3# is the same as #3xx1/10#

Putting all of this together gives.

#0.4xx0.3" "=" "4xx3xx1/10xx1/10#

#12xx1/100 = 0.12#
