 Absolute value of rational numbers The absolute value of a number is its distance from zero on the number line. The symbol for absolute value is ||. Evaluate $|\frac{1}{2}|$ The distance from zero to 1/2 is 1/2. Therefore $|\frac{1}{2}|=\frac{1}{2}$ Evaluate $|-\frac{3}{2}|$ The distance from zero to -3/2 is 3/2. Therefore $|-\frac{3}{2}|=\frac{3}{2}$
