Answer:
C
Explanation:
An irrational number cannot be shown as a simple fraction. If the number has decimals that are non-repeating (so not 7.85555555... or. 9.121212121...), cannot be shown as fractions (not 1.50000000... as it can be written as 3/2), and does not terminate (aka end). C is the answer you're looking for, as it cannot be shown as a fraction, the numbers after the decimal go on indefinitely, and the number's don't follow a noticeable repeatable pattern.
