  1. A(112)/(9)
  2. B(125)/(6)
  3. C(155)/(9)
  4. D(250)/(9)Correct

Explanation

A pie chart represents a full circle, which is 360 degrees. The sum of degrees for items B, C, D, and E is 90 + 50 + 45 + 75 = 260 degrees. To find the degrees corresponding to item A, subtract the sum of the other items from the total 360 degrees: Degrees for A = 360 - 260 = 100 degrees. To convert this into a percentage of expenditure, divide the degrees for A by the total degrees (360) and multiply by 100: Percentage of A = (100 / 360) * 100 Percentage of A = (10 / 36) * 100 Percentage of A = (5 / 18) * 100 Percentage of A = 500 / 18 Percentage of A = 250 / 9 Therefore, the percentage of expenditure on item A is 250/9. Analyzing the options: A) (112)/(9) is incorrect. B) (125)/(6) is incorrect. C) (155)/(9) is incorrect. D) (250)/(9) matches our calculated value. The final answer is D.
