Show the following numbers on the number line.
(1) $$2.5$$
$$2.5$$ represents a point between $$2$$ and $$3$$ on number line, such that the space between $$2$$ and $$3$$ is divided into $$10$$ equal parts. Hence, each equal part will be equal to one-tenth. Now, $$2.5$$ is the fifth point between $$2$$ and $$3$$.
