Simplify 1\(\frac{1}{2} + 2\frac{1}{3} \times \frac{3}{4} - \frac{1}{2}\)
- A. -2\(\frac{1}{3}\)
- B. -2\(\frac{1}{4}\)
- C. 2\(\frac{1}{8}\)
- D. 2\(\frac{3}{4}\)
Correct Answer: D. 2\(\frac{3}{4}\)
Explanation
1\(\frac{1}{2} + 2\frac{1}{3} \times \frac{3}{4} - \frac{1}{2}\)
\(\frac{3}{2} + \frac{7}{3} \times \frac{3}{4} - \frac{1}{2} = \frac{3}{2} + \frac{7}{4} - \frac{1}{2}\)
= \(\frac{6 + 7 - 2}{4} = \frac{11}{4}\)
= 2\(\frac{3}{4}\)
