1/3 + 2/7 = 7/21 + 6/21 = 13/21
4/7 + 1/3 = get common denominator 12/21 + 7/21 = 19/21 is your answer add
64 over 3 or 21 and 1 thrid
1/7+1/3 first get common denominators 3/21+7/21 add the numerators 10/21
7/8 + 1/3 = 21/24 + 8/24 = 29/24 or 15/24
3 over 21
1/3 + 2/7 = 7/21 + 6/21 = 13/21
It is: 13/21
17 over 21
6/7 + 1/3 = 14/21
4/7 + 1/3 = get common denominator 12/21 + 7/21 = 19/21 is your answer add
1/7 + 2/3 is 17/21
6/7+1/3 = 25/21
64 over 3 or 21 and 1 thrid
1/7+1/3 first get common denominators 3/21+7/21 add the numerators 10/21
7/8 + 1/3 = (21+8) / 24 = 1 5/24.
1/2 + 1/3 * 1/7 = 1/2 + 1/21 = 21/42 + 2/42 = 23/42
