#12#

Explanation:

When multiplying fractions, multiply both their numerators and both their denominators. If we want to write both of the terms as fractions, we would write

#2/3xx18/1#

Which then becomes

#=(2xx18)/(3xx1)=36/3#

This equals #36-:3=12#.

#12#

Explanation:

We can write #18=3xx6#. We should do this because we want to cause cancellation in the denominator of #2/3#.

Also, note that #2/3=2xx1/3#. The whole problem can be written then as

#2xx1/3xx3xx6#

Note that #1/3xx3=1#, so all we are left with is #2xx6xx1=12#.
