The multiplicative inverse of a number is what you multiply that number by to get 1. For the fraction 1/2, the multiplicative inverse can be found by flipping the fraction. Thus, the multiplicative inverse of 1/2 is 2. This is because:
- (1/2) * 2 = 1
In general terms, if a fraction is in the form of a/b, its multiplicative inverse will be b/a. So in this case, you simply reverse the numerator and denominator to arrive at the answer, which is 2.
