In both proofs in what form is the number first written?

Answer and explanation

Correct answer: In lowest fraction form

To prove that a square root such as \(\sqrt{2}\) or \(\sqrt{3}\) is irrational, the proof begins by assuming the opposite: that the number is rational. Every rational number can be written as a fraction \(\frac{m}{n}\), where m and n are integers, n is nonzero, and the fraction is in lowest terms. The lowest-terms condition means m and n have no common factor.

This form is essential because the later argument shows that both m and n must be divisible by the same number, usually 2 for \(\sqrt{2}\) or 3 for \(\sqrt{3}\). That contradicts their being coprime. A decimal or percentage form does not provide this useful coprime condition. Therefore option A, the simplest fraction form, is correct.
