What makes this question wrong?: When you divide a number by
1/2
, the result is
A) half the original number.
B) twice the original number.
C) 50% of the original number.
D) 100% of the original number.
The answer is B because when you divide by 2 you get half of the number. But when you divide by 1/2 you do the opposite, so you multiply by the reciprocal.
