## deenaraeb I need help with recognizing natural numbers, irrational, and rational 9 months ago 9 months ago

Irrational numbers are sometimes approximated by fractions - that can get a bit confusing. $$\pi$$ is sometimes approximated by $$\frac{22}{7}$$ which is close enough for most needs but not accurate. Irrational numbers also include any square root that is not a perfect square. For example $$\sqrt2$$.
