The answer is 6.
This question is asking you to divide 3/7 by 1/14 (because that’s how you calculate how “many” of one number is in another number).
To divide fractions, we keep the first one the same, flip the second one upside down, and multiply them:
3/7 ÷ 1/14 -> 3/7 ÷ 14/1 -> 3/7 * 14/1
When you multiply 3/7 by 14, you get 42/7 = 6.
