Question

The product of the multiplicative inverse of $\frac{1}{2}$ and multiplicative inverse of 2 is

• A. 0.0
• B. $\frac{1}{2}$
• C. 1
• D. 2

Answer 1

The correct option is C 1

Multiplicative inverse of a number is that number which when multiplied with the given number, gives 1.
Multiplicative inverse of $\frac{1}{2}$ is 2, since $\frac{1}{2}\times 2=1$ and multiplicative inverse of 2 is $\frac{1}{2}$, since $2\times \frac{1}{2}=1$
Hence the product of multiplicative inverse of $\frac{1}{2}$ and multiplicative inverse of 2 is 1.
