#1/6#

Explanation:

In order to cancel out fractions, we need to have the same number, or expression, in the denominator. This because any number, except for #0#, divided by itself gives #1#.

Now, we need to find a number, in both the denominator and numerator, which is the same. We can find this number to be #3#, but we have to rewrite the fraction.

#3/18=(1xx3)/(6xx3)#

Now we have a number appearing in the numerator and denominator. So we can separate the fraction and simplify it.

#3/18=(1xx3)/(6xx3)=1/6xx3/3=1/6xx1=1/6#
