multiply both numbers by 10 to make them easier to work with
7.3 x 10 = 73
9.6 x 10 = 96
------
96 x 73=
96x 10= 960
960 x 7= 6720
96x 3 =288
------
Add the following.
6720 ( 70 lots of 96 ) + 288 ( 3 lots of 96 )
to get = 7008
------
because we multiplied them in the beginning we need to divide them back.
7008 ÷ 100 = 70.08.
