Which of the following has terminal decimal representation?

Correct option is B

Concept used:

Terminating decimal means a decimal that can be expressed in a finite number of figures or for which all figures to the right of someplace are zero.​

Solution:

Given options are mentioned below:

$$\frac{2}{7}$$​ ≈ 0.2857 (not continues)

$$\frac{2}{9}$$​ ≈ 0.2222 (continues)

$$\frac{2}{3}$$​ ≈ 0.6667 (continues)

$$\frac{2}{5}$$​ = 0.4

Thus, $$\frac{2}{5}$$​ has a terminating decimal representation.
