Answer :

All you have to do is divide both numbers (ones they both can go in).

Let's try 2.

We get [tex] \frac{3}{9} [/tex].

A number still can go into both numbers evenly.
3 can go into both numbers.

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

Hope this helped :)

to convert a fraction into simplest form, we divide both the numbers by their HCF

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
