Pls tell me what is equivalent to these and tell the right number 27 points

7. (6/8)
8. (2/10)
10. (4/12)
11. (4/8)
13. (10/12)
14. (6/12)
16. (9/12)
17. (5/10)

Byou start by adding them all and setting them equal to 180 since that is half of the total degrees in a circle.(2x+8) + (3x-14) + (3x-14) = 1808x-20 = 1808x = 200x = 25
