To solve: (2 5/4 - 5 1/6 + 3 1/3) / (0.087 + 0.3717 ÷ 0.9) Step 1: Simplify the Numerator Convert each mixed number to an improper fraction: 2 5/4 = 13/4 5 1/6 = 31/6 3 1/3 = 10/3 Rewrite the expression as: 13/4 - 31/6 + 10/3 Find a common denominator (12) and convert: 13/4 = 39/12 31/6 = 62/12 10/3 = 40/12 Now calculate: 39/12 - 62/12 + 40/12 = 17/12 Step 2: Simplify the Denominator The denominator is: 0.087 + 0.3717 ÷ 0.9 First, perform the division: 0.3717 ÷ 0.9 = 0.413 Then add 0.087: 0.087 + 0.413 = 0.5 Step 3: Divide the Numerator by the Denominator Now we have: (17/12) ÷ 0.5 = (17/12) × 2 = 34/12 = 2.833 Answer: The correct answer is A. 2.833 The questions are a bit tricky, you just need to use your brain and stop blaming SOF.
