Evaluate: (2/3 + 1/4) ÷ (5/6 - 1/2).
Answer and explanation
Correct answer: A. 2 3/4
- Step 1: Numerator: 2/3 + 1/4 = 8/12 + 3/12 = 11/12. Denominator: 5/6 - 3/6 = 2/6 = 1/3. Step 2. Divide: (11/12) ÷ (1/3) = (11/12) (3/1) = 33/12 = 11/4 = 2 3/4. Answer: 2 3/4. Why not the others:* 1 1/2 results from an inverted multiplication error; 2 1/4 misses the numerator sum; 3 1/3 is 10/3.
