I've been stuck on this question for a while now, and still don't get it!

10/3=3.333r

3.333r*3=9.999r

Can somebody help me understand where the 0.000000r1 went?

Here is another example:

 

1/9 = 0.1111...

2/9 = 0.2222...

7/9 = 0.7777...

9/9 = 0.9999... = 1

 

So actually 0.999... = 1 

 

So we could use this in your question, 9.999r = 1 

 

So 3.3333r * 3 = 9.999999... = 9 + 0.99999... = 9+1 = 10
