What is the reciprocal of 1/2?

• A. 1/2
• B. 2/1
• C. 1
• D. 0

Answer: (B)

The reciprocal of a number is obtained by flipping the numerator and denominator. For the fraction 1/2, the numerator is 1 and the denominator is 2. To find its reciprocal, you switch these two parts. When you take 1/2 and flip it, you get 2/1. This can also be expressed as simply 2, because 2/1 is the same as 2. Therefore, the correct answer is indeed 2/1. Understanding this concept is valuable because reciprocals have many applications in mathematics, including solving equations and working with ratios and proportions. Knowing how to find the reciprocal of fractions can help you navigate various arithmetic problems effectively.
