How much is 4/7 of 21?

  1. 6

  2. 8

  3. 12

  4. 14

The correct answer is: 14

To solve this problem, we first need to find 1/7 of 21 by dividing 21 by 7, which gives us 3. Then, we can find 4/7 of 21 by multiplying 3 by 4, resulting in 12. Therefore, the correct answer is 12 since 4/7 of 21 is equal to 12. The other options (A, B, and C) are incorrect because they are not the same calculation. For option A, 6 is equivalent to 1/7 of 42, not 4/7 of 21. For option B, 8 is equivalent to 2/7 of 28, not 4/7 of 21. For option C, 12 is equivalent to 4/7 of 28, not 4/7 of 21. Therefore
