To find the difference between 1/4 and 1/2, we need to subtract 1/2 from 1/4. 1/4 - 1/2 Since the denominators are different, we need to find a common denominator. In this case, the least common denominator (LCD) is 4. To convert 1/2 to have a denominator of 4, we multiply both the numerator and denominator by 2: 1/2 * (2/2) = 2/4 Now we can subtract: 1/4 - 2/4 Since the denominators are the same, we subtract the numerators: 1/4 - 2/4 = (1-2)/4 = -1/4 Therefore, the difference between 1/4 and 1/2 is -1/4.
