Ok, so what we want to do here is first remove the repeating decimal.
x=2.16 repeating
10x=21.6 repeating
100x=216.6 repeating
Subtract 10x=21.6 repeating from 100x=216.6 repeating. This will get rid of the repeating numbers.
100x=216.6 repeating
-10x=21.6 repeating

90x=195
Divide both sides by 90.
x=195/90
Now you can simplify that into 13/6.
Answer:
The same is true for comparing irrational and rational numbers. By finding a rational approximation of the irrational numbers, we can compare values such as and . For these numbers we may have to go to a three decimal places for our approximation and the use of a calculator would make sense.
