5/7 + 1/3 = 15/21 + 7/21 = 22/21 = 1 1/21
12/21 - 7/21 = 5/21
1/7 + 1/3 = 3/21 + 7/21 = 10/21
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.
1/6 of 54 = 9 and 1/3 of 21 = 7
21
One third divided by seven = 1/21
7/21 + 3/21 = 1021
5/7 + 1/3 = 15/21 + 7/21 = 22/21 = 1 1/21
12/21 - 7/21 = 5/21
1/3 of 21 = 71/3 of 21 = 71/3 of 21 = 71/3 of 21 = 7
1/7 + 1/3 = 3/21 + 7/21 = 10/21
1/3 - 1/7 = 7/21 - 3/21 = 4/21.
