See a solution process below:

First, convert the mixed number on the right into a decimal:

#-0.2 xx -6 1/2 =>#

#-0.2 xx -(6 + 1/2) =>#

#-0.2 xx -(6 + 0.5) =>#

#-0.2 xx -6.5#

Now, multiply the two numbers in decimal form:

#-0.2 xx -6.5 => 1.3#

#1 3/10 = 1.3#

There is a decimal and a mixed number.
Decide on one format to use - I will choose fractions

#0.2 = 2/10 = 1/5" and "6 1/2 = 13/2#

#-1/5 xx -13/2#

There are no common factors to cancel, so multiply straight across:

#+13/10#

#=1 3/10 or 1.3#
