Four marbles of different colours − red, blue, green, and white are kept at the four points obtained by dividing the number line between 1 and 2 into five equal parts as shown in the figure. Find the colour of the marble, which is kept at the point that represents $\frac{8}{5}$.

85 is an improper fraction and is greater than 1.

85 can be written as 135, which is a mixed fraction.

The number line between 1 and 2 has been divided into five equal parts. The third point represents three parts out of five equal parts, i.e., 35. Since this point is to the right of 1, the fraction represented is 1+35=135. This is the point where the green marble is kept.
