Question:

Select all expressions that are equal to 5/8.

  • A. 1/8 + 1/8 + 1/8 + 1/8 + 1/8
  • B. 2/4 + 3/4
  • C. 1/8 + 2/8 + 3/8
  • D. 4/8 + 1/8
  • 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):

  • Option A and D are correct.
