## Answer :

Let's try 2.

[tex]6/2=3\\18/2=9[/tex]

We get [tex] \frac{3}{9} [/tex].

A number still can go into both numbers evenly.

3 can go into both numbers.

[tex]3/3=1\\9/3=3[/tex]

We finally get [tex] \frac{1}{3} [/tex].

Hope this helped :)

HCF of both these numbers is 6.

Thus we divide them by 6

6/6 = 1

18/6 = 3

Thus the answer is 1/3
