Answer 12

sorry for being facetious, but I won't apologize to 3.5 for calling it irrational. geez man, why can't you round off yourself already?

A number is said to be rational when it can be expressed as a fraction in the form of:
\[\frac{ p }{ q }\]
where p and q are integers and q ≠ 0

in this form, p is referred to as the numerator and q denominator

➤ the resulting decimal expansion MUST not contain a non-terminating or infinitely repeating numbers for it to be considered as "rational."

The set of all rational numbers is called "rationals," that is expressed as in a field as ℚ, which can be translated to "ratio" from the German word QUOTIENT.
