(#22) Ok first, before we answer anything, let's get organized. All the numbers are out of order and can be very confusing, so lets put them in ascending(rising) order from 0 to 11. That would result in: 0, 0, 1, 2, 2, 2, 2, 2, 3, 4, 4, 4, 4, 5, 5, 6, 8, 9, 11. Now that its in order, its easier to see how many dots to put on top of each number. You would put two on top of 0, one on top of 1, five on top of 2, and so on.
You typically apply the same rules as you would for 'regular' fractions.
So you can multiply numerator and denominator by the same value if needed. If you want to add fractions you must make sure the denominators are the same, etc.
The value you multiply by can be an algebraic expression.
