Hi there!
I can't post a drawing for this, but I will try to explain using my own words on what 6/9 is in it's simplest form.
The number three can go into 6 and 9. Three goes into 6 twice, and it goes into 9 three times.
So our simplified answer is 2/3.
In decimal form this is 0.66666667 (repeating decimal but rounded off to 0.6667)
Hope this helps!
