J II, III, IV and V only

Answer 1

The correct option is J.II, III, IV and V only.

Explanation:

A rational number are those numbers that can shown in a p/q form or as the ratio of two numbers.

The numbers that cannot be shown as the ratio of two numbers are known as irrational.

Consider each number at a time:

`√(49) =7\equiv 7:1`

`0.287=(287)/(1000)`

`\sqrt{(9)/(16)}=(3)/(4)\equiv 3:4`

`25\equiv 25:1`

Thus, the numbers that are rational are II, III, IV and V.

The correct option is J.
