Step 1

Let's write down these fractions:

From here, we can see that we are dealing with fractions with like denominators.

Step 2

Since the denominators are the same, we can just subtract the numerators together and keep the denominators the same. This is illustrated below:

Step 3

Now, by subtracting 5 with 1, we have the fraction as ⁴/₈:

Step 4

Notice that we can simplify this fraction, by dividing both the numerator and denominator with 4. This gives the fraction, ¹/₂:

Step 5

Here, we can no longer able to further simplify ¹/₂. Therefore, the answer is D.
