To find one third of 21, you would divide 21 by 3. This calculation gives you 7, which is one third of 21. In mathematical terms, 1/3 of 21 is equal to 7.
To add one third and one seventh, we need to find a common denominator. The least common multiple of 3 and 7 is 21. So, we can rewrite one third as 7/21 and one seventh as 3/21. Adding these fractions together, we get 7/21 + 3/21 = 10/21. Therefore, one third plus one seventh is 10/21.
One third divided by seven = 1/21
One third of 63 = 21
a third of 21 is 7
7 is one third of 21. Then, you would have 14 left behind because 7 times 3 is 21 and 7+7+7=21.

33.3% of 21 = 33.3% * 21 = 0.333 * 21 = 6.993
To solve this expression, we first find one third of 21 by dividing 21 by 3, which equals 7. Then we double 7 to get 14. Finally, subtracting 3 from 14 gives us the final answer of 11. Therefore, you are 11.
