Final answer:
If 100 is divided by half, the result is 200, since dividing by one-half is the same as multiplying by 2.
Step-by-step explanation:
When 100 is divided by half, it implies multiplying 100 by 2, because dividing by a fraction is the same as multiplying by its reciprocal. The reciprocal of ½ is 2. Therefore, 100 divided by ½ equals 100 × 2, which is 200.
