2/7 +2/3 = 6/21 + 14/21 = 20/21
14 over 21 or 14/21 in simplest form is 2/3 or 2 over 3
2/3 x 21 = 14
2/3 - 4/7 = 14/21 - 12/21 = 2/21
1 over 21. 5/7 - 2/3 = 15/21 - 14/21 = 1/21
(20/21)/(2/3) = (20/21) x (3/2) = 10/7 = 1 and 3/7 = 1.428571429
6/7 - 2/3 = 18/21 - 14/21 = 4/21
6/7 - 2/3 = 18/21 - 14/21 = 4/21
1/3 + 2/7 = 7/21 + 6/21 = 13/21
Yes and it is 2/3
2/3 + 24/7 = 86/21 or 42/21
14/21 + 9/21 = 23/21
