Final answer:
Options B) 2 - 3/2, C) 1/4 * 2, and D) 4 ÷ 8 each simplify to 1/2 when using addition, subtraction, multiplication, and division.
Step-by-step explanation:
To find which mathematical expression simplifies to 1/2, we will evaluate each option using addition, subtraction, multiplication, and division:
- A) 3 + 1/2 would equal to 3.5, which is not equal to 1/2.
- B) 2 - 3/2 is equivalent to 2 - 1.5, which simplifies to 0.5 or 1/2.
- C) 1/4 * 2 is the same as 1/4 times 2/1, which simplifies to 1/2.
- D) 4 ÷ 8 is the same as 4/8, which reduces to 1/2.
Based on this evaluation, options B, C, and D simplify to 1/2.
