Final answer:
To perform the calculation 4/8 - 2/8, subtract the numerators after ensuring the denominators are the same. Simplify the resulting fraction if possible.
Step-by-step explanation:
To perform the calculation 4/8 - 2/8, you need to subtract the two fractions. To do this, make sure the denominators are the same. In this case, the denominators are already the same, so you can subtract the numerators. 4-2=2. The result is 2/8. However, the fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2. 2/8 divided by 2/2 equals 1/4. Therefore, 4/8 - 2/8 equals 1/4.
