13/20
No because: 4/5 = 0.8 and 4/8 = 0.5
8 eighteenths plus 3 eighteenths ie 11/18
3 equivalent fraction of 4 over 9 = 8/18, 12/27, 16/36
That can't be simplified any more.

2/4 or 1/2
13/20
No because: 4/5 = 0.8 and 4/8 = 0.5
2/7 times 4/5 = 8/35
4/5 - 1/8 = 32/40 - 5/40 = 27/40
8 eighteenths plus 3 eighteenths ie 11/18
3 equivalent fraction of 4 over 9 = 8/18, 12/27, 16/36
0.8
114/5= 11.8
That can't be simplified any more.
