Answer:
B. π
Explanation:
"Like all real numbers, irrational numbers can be expressed in positional notation, notably as a decimal number. In the case of irrational numbers, the decimal expansion does not terminate, nor end with a repeating sequence. For example, the decimal representation of π starts with 3.14159, but no finite number of digits can represent π exactly, nor does it repeat. Conversely, a decimal expansion that terminates or repeats must be a rational number. These are provable properties of rational numbers and positional number systems, and are not used as definitions in mathematics." -Wikipedia
So Wikipedia is telling you that there is no way that π can be placed as. No fraction can make π exactly or any decimal because π is infinite.
is a common fraction people use for π but it actually equals up to 3.142857... with the decimal 142857 repeating.
Our answer must be B. π
