#1107/20# or #55 7/20#

Explanation:

First, we must convert the mixed fractions to improper fractions by multiplying the integer portion of the mixed fraction by the correct form of @#1# and adding to the fraction portion of the mixed fraction:

#(16/16*7 + 11/16)*(5/5*7 + 1/5)#

#(112/16 + 11/16)*(35/5 + 1/5)#

#123/16 * 36/5#

We can now multiply the numerators and denominators:

#(123 * 36)/(16 * 5)#

#4428/80#

#4/4 * 1107/20#

#1 * 1107/20#

#1107/20#

or

#1100/20 + 7/20#

#55 + 7/20#

#55 7/20#
