Yes it Can!.

First check to see if it's divisible by 3. How do you do that.Add the digits together and if their sum is divisible by 3, then the whole number is divisible by 3. So, the first number is 45. Add 4 +5=9. is 9 divisible by 3? yes, because 9/3=3. Therefore the whole number of 45 is divisible by 3. So, 45/3=15 and 15/3=5

Now, do the same thing with 99. 99/3=33. And 33/3=11. And that's the end of the road.

So, 45/99=5/11
