J II, III, IV and V only

Answer 1

Answer:

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

Step-by-step 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:

$\sqrt{49} =7\equiv 7:1$

$0.287=\frac{287}{1000}$

$\sqrt{\frac{9}{16}}=\frac{3}{4}\equiv 3:4$

$25\equiv 25:1$

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

The correct option is J.
