correct me if im wrongg!!!
It is not as tough a problem as it seems to you. You can easily grasp the problem, once it is done,
9 5/9 - 6 5/6 = 86/9 - 41/6
= (172 - 123)/18
= 49/18
= 2 13/18
I hope that the simplification process is simple enough for you to understand. I also hope that this is the answer that you were looking for and the answer has actually come to your desired help.
3 2/3 = 3x3=9+2=11/3
4 2/5= 4x5=20+2=22/5
Answer: y = 57°
Explanation: 180-114 = 66°
A triangle has a total of 180° so 180-66 = 114
114 / 2 = 57° (because angles y and y have the same value)
Hope this helps :)
