To subtract 1/4 from 3/4, you need to have a common denominator. Both fractions already have a denominator of 4, so you can proceed with the subtraction:
3/4 - 1/4 = (3 - 1)/4 = 2/4
However, the fraction 2/4 can be simplified further by dividing both the numerator and denominator by their greatest common divisor, which is 2:
2/4 = 1/2
Therefore, 1/4 - 3/4 = 1/2.
