Neither,
Both fractions reduce to 3/7, so they are equal.
Yes, it is. 6/21 =2/7 =4/14
6 over 4 is the same as 21 over 14 because if you set it up as a proportion and do 6*14 and 21*4 it would equal the same thing (which would be 84)
9/6 = 21/n3/2 = 21/n Since 3 x 7 = 21, then n must be 14 (2 x 7) and we have:3/2 = 21/14 or 9/6 = 21/14.
They're equal.
14 x 1/6 = 21/3
6/14 = 3/7= 9/21
The sum of 3/14 and 13/21 is 5/6.
No
6/7 - 2/3 = 18/21 - 14/21 = 4/21
6/7 - 2/3 = 18/21 - 14/21 = 4/21
greater than
Yes.
