Divide 30 by half

Answer 1

The answer is 1. Division by a is equivalent to multiplication by 1/a. Or, to put that in other words (let b = 1/a), division by 1/b is equivalent to multiplication by b. So, division by 1/2 is equivalent to multiplication by 2. 1/2 multiplied by 2 = 1. Another way to look at it is: how many halves in one half? Answer = 1.
