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)
87/21 - 73/21 = 14/21 = 2/3
Expressed as a proper fraction in its simplest form, 10/15 + 4/14 = 20/21.
4/7, 8/14, 12/21
6/7 - 2/3 = 18/21 - 14/21 = 4/21
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)
4/9 * 3/14 = 2/21
No
2/3 - 4/7 = 14/21 - 12/21 = 2/21
15/14 * 21/10 = 3/14 * 21/2 = 3/2 * 3/2 = 9/4
Yes.
-21/14 + -1/14 = -22/14 or -1 and 4/7
87/21 - 73/21 = 14/21 = 2/3
6/7 - 2/3 = 18/21 - 14/21 = 4/21
6/7 - 2/3 = 18/21 - 14/21 = 4/21
Expressed as a proper fraction in its simplest form, 10/15 + 4/14 = 20/21.
