Rationalize the denominators of the following:

(i) (ii)

(iii) (iv)

Recall, π is defined as the ratio of the circumference (say c) of a circle to its diameter (say d). That is, This seems to contradict the fact that π is irrational. How will you resolve this contradiction?

Represent on the number line.
