Final answer:
The ratio 6:12 simplifies to 1:2, by dividing both terms by their greatest common divisor (6), making option B the correct answer.
Step-by-step explanation:
The ratio 6:12 in simplest form is 1:2. To simplify a ratio, you divide both terms by their greatest common divisor (GCD). In this case, both 6 and 12 can be divided by 6, which is their GCD. So, when you divide both numbers by 6, you get:
- 6 ÷ 6 = 1
- 12 ÷ 6 = 2
Therefore, the ratio of 6 to 12 simplifies to 1:2, which corresponds to option B.
