Answer
5/2
Work Step by Step
To find the absolute value of a given expression we need to define what is the absolute value function. The absolute value of a number is its distance from the origin.
|x| = 0 if x = 0;
|x| = -x if x < 0;
|x| = x if x > 0;
a = 1/4, b = 11/4
|a-b| = |1/4 - 11/4| = |-10/4| = |-5/2| = -(-5/2) = 5/2 , (as -5/2 < 0)
