Which of the following contains only rational numbers?

0, 1, √3, pi
0, 1, 1/2, √2
1, 2, 3, 4
1/2, 2/4, 3/4, 5/2

The correct answer is: 1/2, 2/4, 3/4, 5/2

Rational numbers are numbers that can be expressed as a ratio of two integers. Option A is incorrect because √3 and pi are both irrational numbers that cannot be expressed as a ratio. Option B is incorrect because √2 is also irrational. Option C is incorrect because again, all of the numbers listed are whole numbers and not ratios. Option D is the only option that contains numbers that can be expressed as ratios, making it the correct answer.
