Answer:
It is a rational number.
Step-by-step explanation:
A rational number means it can be expressed in the form
[tex] \frac{p}{q} [/tex]
which it clearly can, as 3.14 as a fraction results in
[tex] \frac{157}{50} [/tex]
A whole number and an integer mean the same; a number without decimals or fraction. Clearly 3.14 is not a whole number and not an integer as it has decimals.
An irrational number is the opposite of the said above rational number; it cannot be expressed as a fraction.
Hence, 3.14 is a rational number.
