Answer 7

oh thats terrible :/
Anyway, a rational number is one which can be written in fraction form, where both, the numerator and denominator are whole numbers.. e.g. 2/3, 4/7
and irrational numbers are those which cannot be written into fractions like above, for e.g. π, because π is a never ending number, and you cannot write a never ending number in fraction form
