12. 21 / 7 = 3 and 4 X 3 = 12
There are: 14/7 = 2
Two sevens = 14 is an integer and not a fraction. However, it can be expressed in rational form as 14/1 which cannot be simplified.
1 + 7 - 3*7 = 8 - 21 = -13
120.29 or 120 with a remainder of 2.

8/3 x 10/7 = 80/21 = 3 and 17/21
12. 21 / 7 = 3 and 4 X 3 = 12
2/14 3/21 4/28 5/35 6/42 7/49
Why does it say sevens sevens it should say seven sevens.
14 and 11 21sts 140/21 + 165/21 = 305/21 or 14 and 11/21
13 and 17/21
There are: 14/7 = 2
Two sevens = 14 is an integer and not a fraction. However, it can be expressed in rational form as 14/1 which cannot be simplified.
34/7 + 22/3 = 25/7 + 8/3 = 75/21 + 56/21 = 131/21 = 65/21
5/7 of 21 would be 15. (if that's what you're asking)
1 + 7 - 3*7 = 8 - 21 = -13
