A number line shows points A, B, C at -1/2, √2, and 7/4 respectively. (√2 is about 1.41 and 7/4 = 1.75.) Which point represents an irrational number?

Question

Accepted Answer

Point B. A = -1/2 and C = 7/4 are rational. B = √2 is irrational, so point B is the irrational one.

A number line shows points A, B, C at $- \frac{1}{2}, 2$ , and $\frac{7}{4}$ respectively $. (2$ is about 1.41 and $\frac{7}{4} = 1.75$ .)
