• E. 4/7 + 1/1

Solution:

Let's review each option one by one.

Option A

• 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 5/8
• => (1 + 1 + 1 + 1 + 1)/8 = 5/8
• => (5)/8 = 5/8 (True)

Thus, Option A is correct.

Option B

• 2/4 + 3/4 = 5/8
• => (2 + 3)/4 = 5/8
• => 5/4 = 5/8 (False)

Thus, Option B is incorrect.

Option C

• 1/8 + 2/8 + 3/8 = 5/8
• => (1 + 2 + 3)/8 = 5/8
• => 6/8 = 5/8 (False)

Thus, Option C is incorrect.

Option D

• 4/8 + 1/8 = 5/8
• => (4 + 1)/8 = 5/8
• => 5/8 = 5/8 (True)

Thus, Option D is correct.

Option E

• 4/7 + 1/1 = 5/8
• => 4/7 + 7/7 = 5/8
• => (4 + 7)/7 = 5/8
• => 11/7 = 5/8 (False)

Thus, Option E is incorrect.

Final Answer(s):
