Show $\dfrac{0}{10}, \dfrac{1}{10}, \dfrac{3}{10}, \dfrac{5}{10}, \dfrac{7}{10}$ and $\dfrac{10}{10}$ on a number line.

Draw a straight line and mark a point O on it representing 0. Mark a point A on the right of O at unit length so that OA represents 1.

Now divide the line segment OA into 10 equal parts. Each part represents $\dfrac{1}{10}$.

Starting from O, mark the points at $\dfrac{0}{10}$ (= 0), $\dfrac{1}{10}, \dfrac{3}{10}, \dfrac{5}{10}, \dfrac{7}{10}$ and $\dfrac{10}{10}$ (= 1).

Hence, the fractions $\dfrac{0}{10}, \dfrac{1}{10}, \dfrac{3}{10}, \dfrac{5}{10}, \dfrac{7}{10}$ and $\dfrac{10}{10}$ are represented on the number line as shown above.
