Answer:

  • D. 1/4 and 9/36

Step-by-step explanation:

If two ratios make a proportion then it can be shown as:

  • a/b = c/d ⇒ ad = bc

Let's verify the answer choices with this method

A. 1/4 and 5/25

  • 1*25 = 4*5
  • 25 = 20, incorrect, not a proportion

B. 1/4 and 7/24

  • 1*24 = 4*7
  • 24 = 28, incorrect, not a proportion

C. 1/4 and 10/48

  • 1*48 = 4*10
  • 48 = 40, incorrect, not a proportion

D. 1/4 and 9/36

  • 1*36 = 4*9
  • 36 = 36, correct, this is a proportion
